| Thiamin | 3.1 mg | Energy metabolism | Supports nervous system 🧠 |
💡 Expert Insight: Beef liver is a nutritional powerhouse packed with high-quality protein, making it ideal for muscle growth and repair in dogs of all ages.
⚠️ Yes, You Can Give Your Dog Too Much of a Good Thing (Vitamin A Toxicity Explained)
Here’s the conversation most treat articles skip entirely: there’s absolutely such a thing as too many liver treats. More commonly, over-supplementation of vitamin A for weeks to months eventually results in a poor hair coat, rough or dry skin, weakness, weight loss, constipation, excessive bone development, and painful or limited movement.
Vitamin A is fat-soluble, meaning it is stored in your dog’s body and excess amounts will accumulate over time. Therefore if your dog receives an ongoing high amount of liver, your dog could start to develop symptoms of vitamin toxicity.
Excessive vitamin A intake during pregnancy has been associated with cleft palate formation and other fetal abnormalities.
But here’s the reassuring news: It is highly unlikely that a dog will suffer toxicity from a single sitting of liver. If your dog stole a bunch of liver treats, you’re more likely to deal with explosive poos.
| Dog Size | Recommended Daily Liver Limit | Training Session Amount | 💡 Safety Tip |
|---|---|---|---|
| Small breeds (under 20 lbs) | Half ounce maximum | 3-5 small pieces | Break treats into tiny bits 🔪 |
| Medium breeds (20-60 lbs) | One ounce maximum | 8-12 small pieces | Count treats during training 📝 |
| Large breeds (over 60 lbs) | One to two ounces | 15-20 small pieces | Use as high-value rewards only 🎯 |
| Puppies (any size) | Less than one ounce | Very sparingly | Growing bones are vulnerable 🐶 |
💡 Expert Insight: To avoid vitamin A overdose, for a small breed dog, 1 to 2 liver treats each week are recommended, for medium sized dogs, 3 to 4 treats and for big dogs 5 to 6 treats.
🧬 Certain Breeds Should Think Twice Before Reaching For The Liver Jar
This is the warning that doesn’t appear on any treat packaging, but every dog owner should know. In the past 10 years, there has been an apparent rise in the number of dogs and breeds that are being diagnosed with copper hepatopathy.
Copper storage disease occurs when copper is stored in the liver, causing liver damage, scarring and leading to liver disease which can be fatal.
It would be helpful for pet food manufacturers to monitor the copper concentration of the ingredients they are using, especially organ meat such as beef liver.
For copper, there is no upper nutritional limit for AAFCO nutritional profiles. It is thought that this can cause an oversupply of copper in pet food which leads to the potential for copper to accumulate.
| Breed at Higher Risk | Special Considerations | 💡 Recommendation |
|---|---|---|
| Bedlington Terriers | Genetic COMMD1 mutation | Avoid liver treats entirely 🚫 |
| Labrador Retrievers | Increasing diagnosis rates | Consult vet, limit treats significantly 🩺 |
| Doberman Pinschers | Females especially affected | Test for copper storage disease 🔬 |
| West Highland Terriers | Breed predisposition | Use alternative protein treats 🍗 |
| Dalmatians | Prone to copper accumulation | Monitor liver enzymes regularly 📋 |
| Skye Terriers | Genetic susceptibility | Consider liver-free alternatives 🥕 |
💡 Expert Insight: Some food items are particularly high in copper, including organ meats. Beef liver is a common ingredient in many training treats. These foods should be avoided if your dog is predisposed to, or has been diagnosed with, copper-associated hepatopathy.
🦠 The Raw Truth About Freeze-Dried Treats and Bacteria
Let’s address something the pet industry doesn’t love talking about. “Freeze-drying alone, without a prior heating/cooking step, is not an effective way to eliminate microbial pathogens” like Salmonella, E. coli and Listeria, says veterinary nutritionist Dr. Megan Shepherd.
Research indicates that freeze-drying can preserve harmful bacteria, just as it preserves nutrients. The freeze-drying process does not kill these pathogens, meaning that while the food may be preserved effectively, it can still pose a risk of contamination.
However, context matters enormously here. There has never been a Stewart recall, according to research tracking recalls since 2009. Their consistent safety record suggests their manufacturing processes effectively manage contamination risks.
It is recommended to wash all work surfaces, utensils, hands and food bowls with hot, soapy water after handling freeze-dried meats and poultry.
| Safety Concern | Reality Check | 💡 Practical Advice |
|---|---|---|
| Bacterial contamination | Possible in any raw product | Wash hands after handling 🧼 |
| Pathogen survival | Freeze-drying preserves bacteria | Store properly, check expiration 📅 |
| Human transmission | Risk to immunocompromised people | Supervise treat time with children 👶 |
| Storage requirements | Cool, dry environment needed | Keep container sealed tight 🏠 |
💡 Expert Insight: Immunocompromised individuals, young children, and elderly family members may be more susceptible to foodborne illnesses and should take extra precautions when handling freeze-dried raw treats.
📜 Understanding What The FDA Actually Requires (And What They Don’t)
The regulatory landscape for pet treats often surprises people. FDA regulates animal food to ensure that it’s safe for the billions of animals in the U.S. FDA is responsible for making sure animal food is safe to eat, produced under sanitary conditions, free of harmful substances, and labeled appropriately and truthfully.
While there is no pre-market approval required for pet food products, the FDA is charged with ensuring pet food is safe according to the Federal Food, Drug and Cosmetic Act and Food Safety Modernization Act.
The Food Safety Modernization Act of 2011 created new requirements and mandatory product safety standards for virtually all U.S. pet food manufacturers. The focus for human and animal food under the law is prevention of illness, rather than reacting and correcting issues that arise.
The FDA ensures that the ingredients used in pet food are safe and have an appropriate function in the pet food. Many ingredients such as meat, poultry and grains are considered safe and do not require pre-market approval.
| Regulatory Body | What They Do | What They Don’t Do | 💡 Implication |
|---|---|---|---|
| FDA | Sets safety standards, inspects facilities | Pre-approve every product | Trust established brands 🏭 |
| AAFCO | Creates nutrient guidelines | Approve or certify products | Guidelines aren’t law 📝 |
| State agencies | Register products, inspect quality | Oversee all label claims | Rules vary by state 🗺️ |
| FSMA | Requires food safety plans | Eliminate all risk | Prevention-focused approach 🛡️ |
💡 Expert Insight: Typical dog food is not subject to the same scrutiny, regulation, and rule-enforcement that applies to human food. Typical dry and canned pet food is subject to the same regulations as commercial animal “feed.”
🎯 The Right Way To Use These Treats Maximizes Training Success
Professional trainers know that how you use a treat matters as much as which treat you choose. These multi-use dog training treats can also serve as a meal topper. Just sprinkle the leftover morsels onto their food once you reach the end of the tub.
Treats should take up no more than 10% of total daily caloric intake. This golden rule applies regardless of how healthy the treat appears.
Stewart recommends the following serving up to 3 times per day: up to 30 lbs, 1 to 2 treats; 30 to 60 lbs, 2 to 4 treats; over 60 lbs, 4 to 6 treats.
| Use Case | Best Practice | Treat Amount | 💡 Pro Tip |
|---|---|---|---|
| Basic training | Break into tiny pieces | 1/4 of full treat per reward | Small rewards maintain value 🎯 |
| High-distraction work | Use full pieces strategically | Full treat for jackpot rewards | Save for breakthrough moments 🌟 |
| Meal topper | Crumble over kibble | Few crushed pieces | Encourages picky eaters 🍽️ |
| Enrichment toys | Stuff in Kongs | Several small pieces | Mental stimulation bonus 🧩 |
| Medication hiding | Wrap around pills | One piece per dose | Strong smell masks medicine 💊 |
💡 Expert Insight: Lots of pet parents use liver treats as training treats, but during training you will be using a lot of treats and too much liver in one sitting is likely to upset your dog’s tummy.
💰 Size Options Give You Flexibility Without Sacrificing Freshness
Stewart offers multiple container sizes to match your training intensity and storage needs. Available sizes include tubs at 2 oz., 4 oz., 12 oz., 14 oz., and 21 oz., plus resealable pouches at 4 oz. and 8 oz.
The 14 oz tub contains approximately 315 treats, providing about a 2 month supply for regular training use.
One common complaint worth noting: Some users report the products do not hold their form well, with containers sometimes containing mostly crumbs. This is a characteristic of freeze-dried products generally rather than a defect, and the crumbled pieces work perfectly as meal toppers.
| Container Size | Approximate Treats | Best For | 💡 Value Consideration |
|---|---|---|---|
| 2 oz tub | ~45 pieces | Trial size, travel | Test before committing 🧪 |
| 4 oz tub/pouch | ~90 pieces | Casual training | Good starter option 👍 |
| 12 oz tub | ~270 pieces | Regular trainers | Better per-treat value 💵 |
| 14 oz tub | ~315 pieces | Professional use | Most popular size ⭐ |
| 21 oz tub | ~470 pieces | Multi-dog households | Best bulk value 🏆 |
💡 Expert Insight: These treats do not contain any antibiotics, steroids, or preservatives. The tub is BPA-free to ensure safety for your pet.
❓ Can I Give These To My Cat Too?
Surprisingly, yes. Cats love these and they are safe as a healthy cat treat for your feline friends. The single-ingredient formula makes them appropriate for cats who can benefit from the same high-protein, low-carb reward.
The same portion cautions apply, however. Cats are smaller than most dogs, so even tinier pieces are appropriate. One small crumb can be a sufficient reward during training sessions.
🔬 What Stewart Does Differently From Other Freeze-Dried Brands
Since 1973, the recipe hasn’t changed. This consistency represents a commitment to a formula that works rather than constantly chasing trends.
The treats are freeze dried in small batches, which allows for better quality control compared to mass production methods.
As pet parents too, we know that peace of mind is important. Rest assured that our quality standards with USDA-certified ingredients ensure that you’re feeding safe dog treats to your fur family.
| Manufacturing Standard | What It Means | 💡 Benefit |
|---|---|---|
| Small batch processing | Individual attention to quality | Fewer contamination opportunities 🔍 |
| USDA-certified liver | Meets human food safety standards | Ingredient you can trust 🏅 |
| Made in Dayton, Ohio | Domestic production oversight | US regulatory compliance 🇺🇸 |
| Resealable containers | Freshness preservation | Treats stay aromatic longer 🔐 |
Your dog’s enthusiasm for Stewart beef liver treats is entirely justified by the nutritional profile and palatability these single-ingredient rewards deliver. The five-decade safety record speaks volumes about manufacturing consistency and quality control. However, responsible pet ownership means understanding the limitations too: By understanding proper preparation methods and portion sizes, you can safely turn this potential superfood into a beneficial treat for your dog.
For most healthy dogs without copper sensitivity concerns, these treats represent one of the most effective training tools available. Just remember that even the best things deserve moderation, and your veterinarian remains your best resource for questions about your specific dog’s dietary needs.
