Safe & Toxic Vegetables for Dogs · Homemade Food Guide · Vet-Verified · Full Toxic List
Most vegetables are far safer for dogs than people realize — but a few are genuinely dangerous, and how you prepare them matters almost as much as which ones you choose. This guide covers every vegetable that belongs in a homemade bowl, every one that should never get near it, and the serving rules that most pet sites quietly skip.
Current FDA Alert — Raw Dog Food & Bacterial Contamination Risk
The FDA issued an updated advisory in May 2026 warning pet owners not to feed eight lots of Raaw Energy frozen raw dog food after positive tests for Listeria monocytogenes in products distributed across nine states. The agency noted that infected pets can shed bacteria through feces and saliva even without showing symptoms — putting humans in the household at risk. This follows a September 2025 FDA advisory against Darwin’s Natural Pet Products after Salmonella and Listeria contamination. Raw homemade diets carry the highest contamination risk of any feeding method, particularly for households with elderly individuals, young children, or anyone with a weakened immune system. Lightly cooked and steamed vegetables added to a base of cooked protein are both safer and, in most cases, equally nutritious.
🌱 The Honest Starting Point About Vegetables in Homemade Dog Food
Vegetables are not a nutritional backbone for dogs the way they are for humans — dogs are primarily carnivores whose bodies run on animal protein and fat. But vegetables are a genuinely useful supporting cast: they add fiber for digestive health, antioxidants for immune support, and variety that most dogs seem to genuinely enjoy. The real catch is what gets left off most lists: vegetables alone do not make homemade food complete. A 2025 study found only 6% of homemade dog diets could be considered nutritionally adequate by AAFCO adult maintenance standards. Adding broccoli and carrots to chicken is wonderful — but without a vet-formulated mineral and vitamin supplement, the meal will almost certainly be deficient in calcium, zinc, vitamin D, and selenium over time. Vegetables improve a homemade diet; they do not finish it. That context belongs at the top, not the footnote.
📋 Quick Answers — What Every Dog Owner Wants to Know
These are the questions people search for most when putting together homemade dog food — answered directly, without the jargon.

1
Which vegetables are completely safe for dogs every day? Carrots · Green beans · Cucumber · Zucchini · Peas (fresh or frozen, not canned with salt)These five are the closest thing to a daily vegetable shortlist for dogs. They are the lowest in sugar, highest in fiber relative to their calorie count, and easiest to serve raw without any prep concerns. Veterinary nutritionists most consistently name carrots and green beans when asked what they recommend for daily vegetable additions. Cucumber is particularly useful in summer — it is about 95% water and provides a hydrating crunch with almost no calories. Zucchini is underrated: it contains vitamin C, potassium, and beta-carotene and is gentle enough for dogs with sensitive stomachs. All five can go raw or lightly steamed — no seasoning, no butter, no oil.

Can dogs eat cooked vegetables or only raw? Both are fine — the right choice depends on the specific vegetable · Raw is better for carrots and cucumber · Light steaming is better for broccoli, sweet potato, and spinach · Never add salt, oil, garlic, or butterThere is no single right answer. Raw vegetables preserve more water-soluble vitamins like C and B6, which overcooking destroys. But some vegetables — particularly sweet potato, beets, and Brussels sprouts — are significantly easier for a dog’s digestive system to handle when lightly cooked, and cooking also breaks down cell walls in leafy greens, making nutrients more bioavailable. The rule of thumb: crunchier, water-rich vegetables (carrots, cucumber, green beans) work great raw. Denser, starchier vegetables (sweet potato, beets) should be steamed or baked. What matters most in every case is what you do not add — no salt, no garlic, no onion, no cooking oil, no seasoning of any kind.

How much vegetable can I add to homemade dog food? Vegetables should make up about 2.5–5% of a complete homemade diet by weight · As treats or toppers: no more than 10% of daily calories · A 50 lb dog can safely eat 1–2 cups of low-calorie vegetables per dayVeterinary nutritionists recommend vegetables constitute roughly 2.5–4.5% of a complete homemade recipe by weight — enough to contribute fiber and micronutrients without displacing the protein and fat a dog actually needs. The more practical way to think about it: most dog-safe vegetables run 15–30 calories per cup, so the 10% treat rule is generous in practice. A 50-pound dog eating 1,000 calories per day could have up to 100 calories worth of vegetables — that is several cups of cucumber or green beans. The constraint that actually matters is sugar content, not just total calories. Starchy vegetables like sweet potato and beets have meaningful sugar levels, so keep those to smaller portions (a few tablespoons, not cups) even if the calorie math looks fine.

What vegetables are absolutely off-limits for dogs? Onions · Garlic · Leeks · Chives · Shallots · Wild mushrooms · Unripe tomatoes and tomato plant parts · Raw potatoes · RhubarbThe toxic list is shorter than most people expect, but the items on it are genuinely serious. Every member of the Allium family — onions, garlic, leeks, chives, shallots, scallions — damages red blood cells in dogs, causing a condition called hemolytic anemia. Crucially, cooking does not make these safe: dried onion powder and garlic powder are actually more concentrated and more dangerous than fresh forms. In 2025, Allium toxicity jumped from the 10th to the 5th most-reported dog poisoning category on the Pet Poison Helpline’s annual list. Wild mushrooms are the other frequent emergency — 100 of the estimated 50,000 mushroom species are toxic to dogs, and it is genuinely difficult to tell them apart. When in doubt about a mushroom, keep your dog away from it entirely.

Can I just feed my dog vegetables and protein without supplements? No — this is the single biggest mistake in homemade feeding · A UC Davis review of 200 homemade recipes found 95% were deficient in at least one essential nutrient · Calcium, zinc, vitamin D, and selenium are the most commonly missing · A vet-formulated mineral supplement is not optionalThis is the gap most pet owners discover months too late. The AVMA’s position on homemade diets is that they can absolutely work — but only when properly formulated, which almost universally requires a vet-developed mineral and vitamin supplement added to every batch. A 2025 ACVIM Forum analysis found that approximately 52% of analyzed homemade diets had ten or more distinct nutrient gaps simultaneously. The most critical missing nutrients — calcium, selenium, zinc, and vitamin D — are not found in meaningful quantities in vegetables or lean meat alone. The practical solution is to work with a board-certified veterinary nutritionist (find one at acvn.org) or use a veterinary recipe calculator like Balance.It, which provides a custom supplement alongside a recipe built for your specific dog.

Are frozen or canned vegetables okay for dogs? Frozen vegetables without added sauces or seasoning are excellent — often nutritionally equivalent to fresh · Canned vegetables usually contain added sodium and must be avoided unless labeled “no salt added” · Drain and rinse canned vegetables if you use themFrozen vegetables are one of the most underused shortcuts in homemade dog food. They are harvested and frozen at peak ripeness, which locks in most vitamins — the nutritional difference between frozen green beans and fresh green beans is minimal for dogs. Canned vegetables are the problem: standard canned green beans, for example, can contain 400mg or more of sodium per serving, which is genuinely harmful to dogs, especially those with heart conditions. If you can only find canned in a pinch, look for the “no salt added” label specifically and rinse thoroughly before serving. For dogs with kidney or heart disease, this distinction is not minor — discuss any sodium concerns with your vet before adding any canned vegetables.

Which vegetables are best for dogs trying to lose weight? Green beans are the top veterinary pick for weight management · Cucumber and zucchini add bulk with almost no calories · Some vets use the “Green Bean Diet” — replacing 10–25% of kibble volume with plain green beans to reduce calories while keeping the dog feeling fullThe “Green Bean Diet” is an actual tool used in clinical veterinary settings — not a social media trend. It works because green beans are extremely low in calories (about 17 calories per cup) while providing a high volume of fiber that signals satiety. Replacing a portion of your dog’s kibble with plain steamed or raw green beans cuts the calorie count of the meal without leaving the dog hungry. Veterinarians most commonly start with a 10% replacement and increase only if needed. Cucumber and zucchini serve the same purpose — they are mostly water, very low in calories, and most dogs eat them readily. If your dog is on a weight management plan from your vet, add vegetables as part of that plan — do not use them as an unguided substitution for commercial food without veterinary guidance.

Can puppies and senior dogs eat the same vegetables as adult dogs? Puppies: yes for small amounts of the safest vegetables (carrot, green bean, zucchini), but always check with your vet first · Senior dogs: same safe list applies, but starchy vegetables should be limited for dogs with diabetes or kidney disease · Size of pieces matters more than ever for both groupsThe ASPCA’s treat limit of 5% of daily caloric intake is even more important for puppies, because their daily calorie needs are smaller. A small puppy eating 300 calories per day should receive no more than 15 calories from extras like vegetables — roughly 2 baby carrots or a few green beans. For senior dogs, the main adjustment is medical context: diabetes, kidney disease, pancreatitis, and other common senior conditions significantly change what is appropriate. A senior dog with kidney disease may need to avoid high-phosphorus or high-potassium vegetables. A dog with pancreatitis needs to avoid any vegetable prepared with fat. Always get your veterinarian’s specific guidance before introducing new foods to a puppy or a senior dog with any health condition.
✅ Vegetables Dogs Can Eat — The Complete Safe List
Every vegetable below is confirmed safe for healthy adult dogs. “Safe” means appropriate for dogs without active medical conditions — always check with your vet for dogs with diabetes, kidney disease, pancreatitis, or other diagnosed conditions before adding new foods.
🥕
Carrots — The Daily Staple
Veterinary nutritionists mention carrots more often than any other vegetable when asked what dogs can eat regularly. They are rich in beta-carotene (which converts to vitamin A), provide meaningful fiber for gut health, and the crunchy texture of a raw carrot provides gentle mechanical dental cleaning. At roughly 25 calories per medium carrot, they can be given generously even to dogs on calorie restriction. Baby carrots work as bite-sized treats. Larger carrots should be cut into pieces appropriate for your dog’s size to prevent choking.
✅ Serve raw or lightly steamed, never seasoned. A baby carrot per 10 lbs of body weight is a reasonable daily amount.
⚠️ High in natural sugar for diabetic dogs — check with your vet first if blood sugar is a concern.
🫛
Green Beans — The Weight Management Vegetable
Green beans are the gold standard vegetable in clinical canine weight management. They are exceptionally filling relative to their calorie count — about 17 calories per cup — and contain vitamins A, C, and K alongside iron and manganese. The “Green Bean Diet” used in veterinary practice involves replacing 10–25% of kibble volume with plain green beans to cut calories without leaving a dog hungry. Fresh, frozen (no sauce), and steamed all work. Canned green beans are acceptable only if labeled “no salt added” — standard canned varieties contain sodium levels that are genuinely problematic for dogs.
✅ One of the best additions for overweight dogs. Serve plain — raw, steamed, or frozen. Frozen green beans are a favorite summer treat for many dogs.
⚠️ Canned versions with added sodium are a problem — read the label every time.
🥒
Cucumber — The Hydration Treat
Cucumber is almost entirely water — about 95% — making it one of the most hydrating and lowest-calorie vegetables available for dogs. Slice it thinly for small dogs or cut into chunks for larger breeds. The mild, crunchy nature makes it appealing to dogs who reject stronger-flavored vegetables. It provides small amounts of vitamins K and C, plus potassium. Particularly useful as a summer treat when dogs need extra hydration. The skin is safe, though peeling is fine if preferred.
✅ Excellent for hot weather, picky eaters, and dogs on strict calorie restriction. No preparation needed beyond slicing.
🥦
Broccoli — Safe in Small Amounts Only
Broccoli is nutritionally excellent — vitamin C, vitamin K, calcium, and fiber — but comes with a meaningful caveat. The florets contain isothiocyanate, a compound that causes gas and gastrointestinal irritation in larger quantities. Most veterinary guidance puts the safe ceiling at 10% of daily food intake by volume, with some recommending 5% or less. Steaming broccoli makes it easier to digest than raw, and smaller pieces reduce the likelihood of a dog bolting it down too fast. The stalks are actually safer than the florets in terms of the isothiocyanate content.
✅ Steamed, plain, in small amounts. Focus on the stalks over the florets if your dog tends to have a sensitive stomach.
⚠️ Do not overfeed — consistent large amounts cause significant gastric distress. Keep to under 10% of total meal volume.
🍠
Sweet Potato — Cooked Only, Watch the Portions
Sweet potato is one of the most popular additions to homemade dog food and for good reason — it is rich in beta-carotene, dietary fiber, vitamin C, and potassium. It provides sustained energy from complex carbohydrates and is significantly more digestible than regular potato. The essential rule: always cook it first. Raw sweet potato is too starchy for most dogs to digest well and can cause stomach upset. Baked, steamed, or boiled (without seasoning) are all fine. Mashed sweet potato can be added to food as a binder. Keep portions measured — roughly 1 tablespoon per 10 lbs of body weight is a reasonable starting guide.
✅ Bake, steam, or boil plain — no butter, salt, or any seasoning. One of the most nutrient-dense carbohydrate additions for homemade food.
⚠️ Higher in natural sugar than most vegetables. Limit for diabetic dogs and those prone to weight gain.
🥬
Kale — Occasionally, Not Daily
Kale is nutrient-dense — vitamins A, C, K, and calcium — but it contains calcium oxalates and isothiocyanates that make it unsuitable as a daily vegetable for dogs. Occasional small amounts (a leaf or two, lightly steamed) are fine for healthy dogs. Dogs with a history of calcium oxalate bladder stones or kidney disease should not have kale at all. The oxalic acid in kale can also interfere with calcium absorption if fed in large, repeated amounts. Think of kale as an occasional nutritional boost, not a daily staple.
✅ Small amounts, lightly steamed, on an occasional basis for healthy dogs without kidney history.
⚠️ Not appropriate for dogs with kidney disease, bladder stones, or hypothyroidism. Discuss with your vet first.
🌽
Corn Kernels — Yes; Corn Cobs — Absolute No
Plain cooked corn kernels are safe for dogs — they provide fiber, antioxidants, and some B vitamins. The universal warning applies here with particular emphasis: corn cobs are a veterinary emergency waiting to happen. They do not digest and will block a dog’s intestinal tract, requiring surgical intervention to remove. This distinction is one of the most important things for dog owners to internalize. Kernels cut from the cob and served plain are fine. The cob itself, in whole or broken pieces, can kill a dog and should always be placed immediately in a sealed trash receptacle inaccessible to dogs.
✅ Plain kernels only — cooked, no salt, no butter. Perfect as a food topper or occasional treat.
⚠️ CORN COBS ARE NEVER SAFE. Intestinal obstruction is a life-threatening emergency.
🍅
Tomatoes — Ripe Red Flesh Only
Ripe, red tomato flesh is safe for dogs in small amounts and provides lycopene and vitamin C. The hazard is in the unripe portions and all green parts of the plant — stems, leaves, and unripe tomatoes contain solanine and tomatine, compounds that are toxic to dogs and cause gastrointestinal upset, weakness, and in large amounts, more serious neurological effects. A few pieces of ripe red tomato as an occasional food topper are fine. Any tomato that is still showing green, any part of the plant, or leaves in a tomato sauce are off limits. If your dog has access to a garden tomato plant, ensure they cannot reach it.
✅ Ripe red flesh only, in small amounts as an occasional addition — not a regular ingredient.
⚠️ Unripe tomatoes, stems, leaves, and the plant itself are toxic. If your dog shows weakness or gastrointestinal upset after tomato exposure, call your vet.
🫛
Peas — Fresh or Frozen; Not Canned
Fresh and frozen peas are safe for dogs and provide a useful combination of fiber, protein, and vitamins A, B, and K. Snow peas and sugar snap peas are also fine in moderate amounts. The concerns: canned peas are typically high in sodium and should be avoided unless labeled no-salt-added. Peas also contain purines, which can contribute to uric acid accumulation — dogs with kidney disease or a history of urate bladder stones should not have peas regularly. For healthy dogs, peas are a fine daily addition in reasonable amounts. They are small enough to serve whole as treats or mixed into food.
✅ Fresh or frozen plain peas are great mixed into homemade food. Thaw frozen peas before serving to avoid a cold shock to the stomach.
⚠️ Not recommended for dogs with kidney disease or urate stones. Skip canned peas entirely.
🥒
Zucchini — One of the Most Underrated Additions
Zucchini is perhaps the most underappreciated vegetable in homemade dog food. It is extremely low in calories, gentle on digestion, and most dogs eat it readily. It provides vitamin C, vitamin B6, potassium, and manganese. Raw zucchini can be cut into coin shapes or grated and mixed into food. Steamed zucchini becomes very soft and can be mashed into a food base for dogs who need soft food due to dental issues or age. Unlike broccoli, it causes very little gas. Unlike sweet potato, its sugar content is minimal. It is the kind of vegetable worth keeping on hand simply because it fills a useful gap in almost every homemade recipe.
✅ One of the best vegetables for homemade food. Raw coins, grated, or steamed and mashed all work well.
🚫 Vegetables That Must Never Go in Dog Food
These are not “use sparingly” items — they are off the table entirely. Several of these appear commonly in cooking, which is why they cause so many accidental poisonings. Contact the ASPCA Animal Poison Control at 888-426-4435 or your vet immediately if your dog has consumed any of these.
🧅
Onions, Garlic, Leeks, Chives, Shallots, Scallions
The entire Allium family is toxic to dogs — raw, cooked, dried, and powdered. The compound N-propyl disulfide (thiosulfate) damages red blood cells, causing hemolytic anemia. Onion and garlic powder are especially dangerous because they are far more concentrated than fresh forms and hide in seasoning blends, broth, and leftovers. In 2025, Allium toxicity jumped from 10th to 5th on the Pet Poison Helpline’s most-reported dog poisoning list. Even a tablespoon of onion in a soup shared with a small dog can be enough to cause a toxic reaction. All forms are toxic: raw, sautéed, caramelized, powdered, in broth — no form is safe.
🍄
Wild Mushrooms
Of the estimated 50,000 mushroom species, approximately 100 are toxic to dogs — and it is genuinely difficult to distinguish harmful from harmless in the field. Wild mushroom toxicity ranges from gastrointestinal upset to liver failure and death depending on the species consumed. Store-bought white button mushrooms (plain, unseasoned) are generally considered safe in small amounts, but wild mushrooms are never safe, period. If you have mushrooms growing in your backyard or garden, check and remove them regularly. Dogs on outdoor walks can and do forage mushrooms faster than owners realize.
🥔
Raw Potatoes and Green Potatoes
Raw potatoes — and any potato showing green skin or a green tinge — contain solanine, a glycoalkaloid that is toxic to dogs and causes vomiting, diarrhea, confusion, and in significant amounts, more serious neurological effects. Fully cooked, plain white or yellow potato in small amounts is generally considered safe for healthy dogs, but raw potato is always off limits. The green portions of any potato, even cooked, should be removed entirely before serving.
🫚
Rhubarb
Rhubarb stalks and especially rhubarb leaves contain oxalic acid and oxalates at levels that are genuinely toxic to dogs, causing kidney damage and symptoms including drooling, lethargy, vomiting, and tremors. Even the stalks, which humans eat safely, are problematic for dogs in any meaningful amount. This is a relatively obscure vegetable in dog food contexts, but backyard rhubarb plants are common and dogs occasionally access them.
🌿
Tomato Plant (Leaves, Stems, Unripe Fruit)
The tomato plant itself — leaves, stems, and green unripe fruit — contains tomatine and solanine, which are toxic to dogs. While ripe red tomato flesh is safe in small amounts, the plant parts are not. If you grow tomatoes, a garden fence that prevents dog access is worth the investment. Gardeners who share their own backyard vegetables with their dogs should be especially careful that no green portions or plant material is included.
🌽
Corn Cobs (Kernels Are Safe — Cobs Are Not)
Corn cobs do not digest and create intestinal obstructions that require surgical removal. This is one of the more frequently seen dog emergencies in veterinary clinics, particularly around summer cookouts. The signs of an obstruction — vomiting, lethargy, straining, loss of appetite — may not appear immediately, but the situation is life-threatening if not addressed. Always place corn cobs directly in a sealed trash bin immediately after eating. The kernels themselves, plain and cooked, are completely safe.

⚠️ The Mistakes That Actually Hurt Dogs
Most vegetable-related dog health problems are not from the vegetable itself — they are from how it was prepared, how much was given, or what it was combined with. These are the most common.
🚫 Adding Vegetables from Cooked Human Meals
This is the source of most allium poisonings in dogs. A roasted vegetable medley, a stir-fry, a soup, mashed potatoes — virtually every savory cooked dish for humans contains some form of onion, garlic, leek, or seasoning blend that includes these ingredients. The toxicity is invisible in the final dish because the vegetables have broken down. A dog stealing a bowl of leftover French onion soup or getting a spoonful of garlic mashed potato has potentially consumed a dangerous dose. Only serve plain, unseasoned vegetables prepared separately for your dog — never from the human cooking pot.
⚠️ Using Canned Vegetables Without Checking the Label
Standard canned vegetables contain added sodium at levels that are problematic for dogs — particularly those with heart disease, kidney disease, or hypertension. A single serving of regular canned green beans can contain 400mg or more of sodium, which represents a significant portion of a dog’s recommended daily sodium limit. If you use canned vegetables, look for labels that specifically say “no salt added” or “low sodium” and rinse the contents before serving. For dogs on a cardiac or renal diet, discuss any canned vegetable use with your veterinarian before adding them.
⚠️ Overfeeding Gassy Vegetables
Broccoli, Brussels sprouts, cauliflower, and cabbage all cause significant gas in dogs when fed in large amounts. The isothiocyanate compounds in these cruciferous vegetables irritate the gastrointestinal lining when consumed in excess. Dogs — especially larger breeds — can experience discomfort, bloating, and excessive flatulence that owners sometimes misread as a food allergy. These vegetables are not harmful in small portions, but the serving size matters considerably. Keep any cruciferous vegetable to under 10% of the meal by volume and introduce them gradually.
⚠️ Thinking Vegetables Alone Make Homemade Food Complete
A homemade meal of chicken, brown rice, and a medley of vegetables looks complete. It is not. A 2025 Texas A&M study confirmed that 94% of owners making homemade dog food are doing it incorrectly — not because homemade food is wrong, but because the most commonly missing nutrients (calcium, selenium, zinc, vitamin D, and appropriate omega fatty acid ratios) are not found in meaningful quantities in vegetables or lean protein alone. If you are feeding homemade food as a primary diet, a vet-formulated mineral supplement is not optional. A board-certified veterinary nutritionist (find one at acvn.org) can formulate a recipe and identify the right supplement for your dog’s specific needs.
🍽️ How to Prepare Vegetables for Dogs — The Essentials
✅ The Universal Rules for Any Vegetable You Serve
- Always plain and unseasoned. No salt, no butter, no garlic, no olive oil, no seasoning blend of any kind. Garlic and onion appear in most commercial seasoning blends — read any label before use.
- Cut appropriately for your dog’s size. A piece that’s fine for a 70-lb Labrador can be a choking hazard for a 10-lb Maltese. Baby carrots and cherry tomato-sized pieces work for small dogs; larger chunks for medium and large breeds.
- Introduce one new vegetable at a time. Wait 24–48 hours before adding another. Watch for digestive changes, vomiting, loose stools, or itching. If any of these appear, stop that vegetable and note it for your vet.
- Raw is fine for most water-rich vegetables; cook the starchy ones. Carrots, cucumber, zucchini, and green beans work great raw. Sweet potato, beets, and dense root vegetables should be cooked.
- Do not overcook. Boiling vegetables until mushy destroys water-soluble vitamins like C and B6. Light steaming (5–7 minutes for most vegetables) preserves nutrition while improving digestibility.
🩺 When to Call Your Vet After a Dog Eats a Vegetable
- Any amount of onion, garlic, leeks, chives, shallots, or scallions — call immediately, even if the amount seems small. Do not wait for symptoms to develop.
- Wild mushrooms — contact the ASPCA Animal Poison Control Center at 888-426-4435 or your vet. Identify the mushroom if possible by taking a photo.
- Any new vegetable that causes vomiting, lethargy, diarrhea, pale gums, or tremors — these symptoms warrant a call regardless of what was eaten.
- A corn cob was swallowed whole or in pieces — this is a potential surgical emergency. Go directly to your vet or an emergency animal hospital, even before symptoms of obstruction appear.

✅ 5-Step Safety Checklist Before Adding Any Vegetable
- Step 1: Check the toxic list first. Onions, garlic, and the full Allium family are never safe in any form — raw, cooked, dried, or powdered. Wild mushrooms are never safe. Corn cobs, raw potatoes, and rhubarb never belong in a dog’s bowl.
- Step 2: Prepare it plain. No salt, no oil, no seasoning, no cooking sauce, no leftovers from a human meal. Set the vegetable aside before adding anything to your own food.
- Step 3: Start small. A small piece, one vegetable at a time, with a 24-hour wait before adding another. Most digestive reactions are mild and temporary — but identifying which vegetable caused them requires introducing one at a time.
- Step 4: Adjust for your dog’s health history. Diabetic dogs need portion control on starchy and sugary vegetables. Dogs with kidney disease should avoid high-phosphorus or high-potassium vegetables. Dogs with a history of bladder stones need to avoid oxalate-rich vegetables. When in doubt, ask your vet first.
- Step 5: Remember that vegetables are a supplement to a complete diet — not a substitute for one. If you feed homemade food as your dog’s primary diet, work with a board-certified veterinary nutritionist and use a vet-formulated mineral supplement in every batch. The most nutritious vegetable medley cannot fix a diet missing calcium, selenium, or vitamin D.
