Ruff Greens vs Dinovite — Ingredients, Reviews & Complaints

Ruff Greens and Dinovite are both powdered nutritional supplements mixed directly into a dog’s existing food. They are heavily advertised on television and online, and both have developed loyal customer bases. But they take fundamentally different approaches to canine supplementation — and they come with very different price tags, ingredient philosophies, return policies, and customer service track records. Before you decide, here are the most important facts to know.

  What is the main difference between Ruff Greens and Dinovite? Ruff Greens: broad-spectrum “complete nutrition” multivitamin supplement — 25+ vitamins/minerals, 15 probiotic strains, 20+ digestive enzymes, Omega 3/6/9 oils — 100% vegan · Dinovite: “targeted support” supplement focused primarily on skin, coat, and gut health — probiotics, prebiotics, Omega-3s from flax, zinc, Vitamin E, kelp — contains yeast and animal-derived ingredients · Ruff Greens aims to replace everything kibble is missing; Dinovite targets the most common complaints (itching, shedding, digestion)

  Ruff Greens VitaSmart, developed by Dr. Dennis Black (a Naturopathic Doctor, not a licensed veterinarian or DVM), is built on the philosophy that commercial kibble — even expensive kibble — destroys live nutrients during high-heat manufacturing, and that dogs need a comprehensive daily supplement to fill every gap. The formula covers a wide nutritional base: over 25 vitamins and minerals from plant-based sources, 15 strains of probiotics, more than 20 digestive enzymes, and a full Omega 3-6-9 oil blend. It is 100% vegan with no meat or meat by-products, no GMOs, and no Chinese-sourced ingredients. Dinovite, created by a professional dog breeder and trainer with over 20 years on the market, takes a narrower focus: it specifically addresses the skin allergy, hot spot, yeast infection, and digestive complaints that are the most common reasons dog owners seek supplements. Its formula uses probiotics and prebiotics for gut support, Omega-3 fatty acids from ground flaxseed for skin and coat, zinc methionine complex for skin health, Vitamin E as an antioxidant, dried kelp, and yeast culture as active gut support — it also offers a 90-day money-back guarantee on first purchases.

  Is Ruff Greens actually good for dogs? Mixed evidence — many owners report improvements in energy, coat, and digestion; some dogs experience digestive upset when starting; not backed by board-certified veterinary nutritionists; over 200,000 dogs reportedly on the product · Key caution: “veterinarian formulated” on Ruff Greens marketing refers to the founder’s naturopathic credentials — not a licensed DVM or veterinary nutritionist · Dogs eating complete and balanced food may not need it at all

  The honest answer is: Ruff Greens has real customers who report genuine positive changes — improved coat shine, better digestion, more energy, less itching — particularly in dogs that were previously eating a low-quality kibble with significant nutritional gaps. For those dogs, adding a broad-spectrum supplement with live probiotics and digestive enzymes may provide measurable benefit. However, critical context matters: the founder of Ruff Greens, Dr. Dennis Black, holds a Naturopathic Doctorate — he is not a licensed Doctor of Veterinary Medicine (DVM) and is not a board-certified veterinary nutritionist (DACVN). The term “veterinarian formulated” as used in Ruff Greens marketing does not mean a DVM reviewed or approved the formula. Per veterinary nutritionists, dogs eating AAFCO-compliant “complete and balanced” food are already meeting their minimum nutritional requirements. Additional vitamin and mineral supplementation can cause imbalances — particularly with fat-soluble vitamins and certain minerals at high doses. Some users also report digestive upset, vomiting, and diarrhea when starting Ruff Greens — often due to the abrupt introduction of probiotics and enzymes. Starting with a smaller dose and gradually increasing tends to reduce this risk. For dogs with existing health conditions, always consult a DVM before adding Ruff Greens.

  Is Dinovite actually good for dogs? Dinovite has the stronger case for itchy, allergy-prone dogs due to its targeted formula · Zinc methionine and Omega-3s from flax are ingredients with documented support for skin health · Key caution: Dinovite contains yeast and yeast culture — this can worsen symptoms in dogs with yeast-related skin infections (a very common cause of itching) · No board-certified veterinary nutritionist on record for the formulation · 90-day money-back guarantee is stronger than Ruff Greens’ policy

  Dinovite has been on the market for over 20 years and has a genuine customer base — over 1 million pets reportedly served — with strong reviews specifically for dogs suffering from chronic itchy skin, seasonal allergies, hot spots, and dull coats. The ingredients its formula relies on — Omega-3 fatty acids, zinc, probiotics, and Vitamin E — do have published scientific support for skin barrier health and immune regulation in dogs. For a dog whose itching stems from nutritional gaps, mild atopic dermatitis, or gut dysbiosis, Dinovite’s targeted formula may produce noticeable improvement. However, there is a significant counter-indication that is frequently overlooked: Dinovite’s formula contains dried yeast and yeast culture as core ingredients. For dogs whose itching and skin problems are caused or worsened by yeast overgrowth — which is actually one of the most common causes of chronic canine skin issues — feeding additional yeast can trigger or worsen flare-ups. Before choosing Dinovite for an itchy dog, your veterinarian should confirm whether a yeast infection is contributing to the skin condition. Dinovite also does not disclose formulation by a DVM or board-certified veterinary nutritionist on its website, though its ingredient list is generally composed of recognized nutritional compounds rather than proprietary blends.

  What are the most common Ruff Greens complaints? Three major complaint categories documented on BBB: (1) auto-subscription billing surprises — the “free trial” automatically converts to a paid recurring subscription; (2) cancellation difficulty — customers report difficulty canceling online with no easy phone option readily displayed; (3) return policy — only the first 30-day supply is eligible for refund; subsequent orders are generally non-refundable even if unopened

  Ruff Greens has a substantial volume of complaints on file with the Better Business Bureau, and the patterns in those complaints are consistent and important to understand before purchasing. The most frequent issue involves the “free trial” offer advertised on television and online: customers order a trial bag paying only shipping, and are enrolled in an automatic monthly subscription that charges approximately $50–$130 per subsequent shipment. Many customers report not fully understanding this when signing up, and not receiving an email warning before the first charge. A second recurring issue is cancellation: Ruff Greens requires customers to cancel by calling their office — canceling through the website account or chat alone has not consistently stopped charges for many customers. A third issue is the refund policy: Ruff Greens officially states it will only refund the first 30-day supply after the trial period; subsequent auto-shipped orders are generally non-refundable even if returned unopened. Practical advice before ordering: Read the terms of the free trial carefully; cancel by phone and keep a record of the confirmation; use a credit card rather than a debit card so you have chargeback rights if needed; do not order a large bundle (Pack Pak) before confirming your dog tolerates the product.

  How much does Ruff Greens cost vs Dinovite per month? Ruff Greens: approximately $50–$130/month depending on dog size and bag volume (subscription); trial available but converts to subscription · Dinovite: approximately $30–$60/month; 15% savings with auto-ship; one-time purchases available · Dinovite is significantly more affordable for most households and offers a stronger 90-day money-back guarantee on first orders · Ruff Greens is roughly 3–5x more expensive per serving than Dinovite

  On a pure cost-per-month basis, Dinovite is substantially more affordable than Ruff Greens for most dog owners. Ruff Greens charges approximately $50 per month for a small dog (around 30 lbs) and significantly more for larger dogs — a single large-dog Pack Pak can run $395 or more upfront, and ongoing subscription pricing runs $100–$130/month for large dogs. Dinovite’s flagship 3-in-1 powder typically costs $30–$60/month depending on dog size, with a 15% discount for subscribers and a flexible delivery schedule of every 30, 60, 90, or 120 days. When comparing both products for a medium-sized 40–60 lb dog on an ongoing basis, most households will spend roughly two to four times more on Ruff Greens than on Dinovite. Dinovite’s 90-day money-back guarantee on first purchases is also meaningfully better than Ruff Greens’ 30-day refund window for first orders. If budget is a significant factor, Dinovite’s value proposition is stronger — particularly if its targeted skin and gut formula aligns with your dog’s specific needs.

  What is comparable to Ruff Greens for dogs at a lower cost? Top alternatives to Ruff Greens at lower cost: Zesty Paws 8-in-1 Multivitamin Bites (~$25–$40/month; includes glucosamine for joints that Ruff Greens lacks) · NaturVet All-in-One (~$20–$35/month; soft chew; vitamins + digestive + joints) · Dr. Harvey’s Canine Health (whole-food meal base mix; for owners who cook for dogs) · Nordic Naturals Omega-3 Pet (pure Omega-3 fish oil; ~$20/month; stronger EPA/DHA than plant-based sources) · A vet-recommended single-strain probiotic (e.g., Purina FortiFlora; clinically proven; ~$1–$2/day)

  Dog owners who want broad-spectrum nutritional support without Ruff Greens’ price and subscription concerns have several well-regarded alternatives. Zesty Paws 8-in-1 Multivitamin Bites are one of the best-selling dog supplements in the United States — they cover vitamins, omega fatty acids, probiotics, and notably include glucosamine, chondroitin, and MSM for joint support, which Ruff Greens does not include despite marketing itself as a comprehensive supplement. NaturVet All-in-One is a convenient soft chew covering four categories (skin/coat, joints, digestion, and vitamins) at approximately half the cost of Ruff Greens. For owners specifically concerned about gut health and documented evidence, Purina FortiFlora is the most clinically studied probiotic supplement available over the counter for dogs — it contains Enterococcus faecium SF68, a strain with multiple published clinical trials supporting its use in canine GI conditions. Unlike Ruff Greens, FortiFlora is backed by clinical trial data and is recommended by veterinarians. Pure fish oil (Nordic Naturals or similar marine-sourced Omega-3 products) provides EPA and DHA in forms more bioavailable than the plant-derived flaxseed Omega-3s used in both Ruff Greens and Dinovite — fish oil is the most effective over-the-counter supplement for skin and coat in dogs according to most veterinary dermatologists.

  Are Ruff Greens and Dinovite FDA-regulated? Neither is FDA-approved as a veterinary drug · Both are sold as dietary supplements for pets — regulated under the FDA’s Center for Veterinary Medicine but held to a lower standard than prescription medications · The FDA does not review or approve pet dietary supplements before they reach the market · Ruff Greens is manufactured in an FDA-registered, GMP-certified facility (manufacturing safety) · Neither product has ever been subject to an FDA recall

  The regulatory landscape for pet dietary supplements in the United States is important context. Unlike prescription veterinary medications, pet dietary supplements are not required to receive FDA approval before being sold. The FDA’s Center for Veterinary Medicine oversees pet food and supplements, but it does not conduct pre-market review or efficacy testing of dietary supplements. What this means in practice: neither Ruff Greens nor Dinovite had to prove to the FDA that their products are effective for the conditions they allude to in their marketing — such as improved coat, energy, or gut health — before selling them. What the FDA does regulate is manufacturing safety and label honesty: pet supplements must be manufactured in sanitary conditions and may not make false claims. Ruff Greens specifically states its product is made in an FDA-registered, GMP (Good Manufacturing Practice)-certified facility in the United States, which is a meaningful manufacturing quality standard. Neither Ruff Greens nor Dinovite has been subject to an FDA recall as of this writing. For voluntary quality assurance, look for the NASC (National Animal Supplement Council) Quality Seal on pet supplements — it indicates the company has passed an independent audit of manufacturing and labeling practices. Always verify the most current regulatory status at fda.gov/animal-veterinary.
