You know that look. The one where your dog sniffs the "premium" kibble you just spent sixty bucks on, huffs a little sigh of disappointment, and walks away. It’s annoying. Honestly, it’s expensive too. Most of us end up down a rabbit hole of toppers and wet food just to get a basic meal into them. That’s usually where Stewart freeze dried dog treats enter the conversation. They aren't some new-age fad launched by a tech startup last week. Stewart (specifically under the Pro-Treat label) has been around since the 70s. Back then, they weren't trying to be "artisanal." They were just making single-ingredient liver treats for trainers.
It works.
The magic—if you want to call it that—isn't in some secret chemical formula. It’s the lack of one. When you look at the back of a standard bag of "bacon-style" dog snacks, you see glycerin, yellow 5, phosphoric acid, and a list of grains that probably shouldn't be there. Stewart basically just takes a piece of beef liver and sucks the water out. That’s the whole trick.
The Science of Cold and Dry
Freeze-drying is weirdly cool. It’s technically called lyophilization. Basically, the raw organ meat is frozen, and then it goes into a vacuum chamber. The ice turns straight into vapor without ever melting into water. This is a big deal because heat is what kills the good stuff. When you cook a treat at high temperatures, you denature the proteins and blast away the vitamins.
Because Stewart freeze dried dog treats don't go through that heat cycle, the nutritional profile stays almost identical to raw meat. But you don't have the "raw meat" mess in your pocket. It’s shelf-stable. It’s lightweight. It’s essentially an astronaut's meal for a Golden Retriever.
Most people don't realize that liver is nature's multivitamin. It is packed with Vitamin A, B12, and iron. It’s potent. You can't just feed your dog a bowl of liver—they’d get a massive stomach ache or even vitamin A toxicity over time—but as a high-value reward, it’s hard to beat.
Why Trainers are Obsessed With the Liver Tub
If you’ve ever been to an agility trial or a basic puppy obedience class, you’ve seen the big blue tub. It’s iconic. There’s a reason professional trainers stick to it. Most treats are crumbly. They fall apart in your pouch, leaving you with a handful of dust and a distracted dog.

Stewart treats have a specific texture. They are spongy but firm. You can snap them into tiny pieces for "rapid-fire" rewarding without the whole thing disintegrating into a powdery mess. This is vital when you’re trying to teach a "heel" or a "stay" and need to deliver the reward within a half-second of the correct behavior.
Comparing Stewart Freeze Dried Dog Treats to the Competition
The market is crowded now. Brands like Stella & Chewy’s, Northwest Naturals, and Vital Essentials are all fighting for shelf space. So, where does Stewart actually sit?
Honestly, they are the "utility" option.
Stella & Chewy’s often adds ingredients—cranberries, probiotics, seeds. That’s fine for a meal, but for a treat, many owners prefer the simplicity of Stewart. If your dog has a sensitive stomach or a specific allergy to chicken, you know exactly what’s in the Stewart Beef Liver tub. Beef. Liver. That’s it.
The price point is also a factor. Freeze-drying is expensive. It takes a long time and uses a lot of energy. However, buying the large 11.5oz or 17oz tubs of Stewart freeze dried dog treats usually brings the cost per ounce down significantly compared to those fancy 2oz bags you find at boutique pet stores.
It’s worth noting that these aren't just for dogs. A lot of cat owners sneak these into their carts too. Cats are notorious for being obligate carnivores, and a piece of freeze-dried wild salmon or liver is often the only thing that gets a finicky feline to pay attention.

The Dust Factor (A Real Talk Moment)
Let’s be real for a second. The bottom of the tub is going to have some powder. It’s the nature of the beast. Since there are no binders—no wheat gluten or gums to hold it together—the friction of the treats rubbing against each other during shipping creates "liver dust."
Don't throw it out.
This is the ultimate hack for the "kibble quitter." Sprinkle that dust over their regular dinner. It’s like parmesan cheese for dogs. It turns a boring bowl of dry pellets into something that smells like a gourmet steakhouse to a canine nose.
Is It Safe? Addressing the Raw Meat Concern
There’s always a debate about raw feeding. Some vets are all for it; others are terrified of Salmonella and E. coli. The benefit of the freeze-drying process used in Stewart freeze dried dog treats is that while the meat is "raw" in terms of its nutritional structure, the moisture content is so low (usually around 5%) that it’s incredibly difficult for bacteria to thrive.
Stewart also uses a process called HPP (High Pressure Processing) for many of their products. This uses extreme pressure to kill pathogens without using heat. It’s a safety net. If you’re worried about handling raw meat but want the benefits of a raw diet, this is the middle ground. It’s clean. You don't need to wash your hands every single time you touch a cube, though it's still good practice.
Picking the Right Protein
Beef liver is the classic, but they’ve branched out. You’ve got:
✨ Don't miss: Wire brush for cleaning: What most people get wrong about choosing the right bristles
- Chicken Breast: Lower fat, good for dogs prone to pancreatitis.
- Wild Salmon: Great for skin and coat, though it smells... well, like salmon.
- Lamb Liver: A solid alternative for dogs with beef allergies.
- Beef Heart: Leaner than liver and very high in taurine.
If you have a puppy, start small. Their stomachs are still figuring out life. A sudden influx of rich organ meat can lead to loose stools. Think of it like a human eating a giant tub of heavy cream—moderation is key.
What Most People Get Wrong About Storage
I see people leave the lids off these tubs all the time. Big mistake. Freeze-dried food is a sponge for moisture. If you live in a humid place like Florida or Houston and leave that tub cracked, those treats will start to absorb the ambient water in the air.
They won't "spoil" immediately, but they lose that signature crunch. They get rubbery. Worse, once moisture is introduced, the shelf life plummets. Keep the lid snapped tight. If you buy the massive tub, consider moving a week's worth of treats into a smaller, airtight mason jar and keeping the big tub sealed in the pantry. It keeps everything fresh.
Actionable Steps for Your Dog’s Training
If you're ready to actually use these effectively, don't just hand them out for free. That’s "welfare" feeding.
- The Jackpot: Use the bigger chunks for when your dog does something truly impressive, like coming back to you when they really wanted to chase a squirrel.
- The Meal Topper: Take those small broken shards at the bottom of the bag and mix them with a little warm water to create a gravy for their kibble.
- The Enrichment Toy: Stuff a few pieces into a rubber toy or a snuffle mat. Because they are dry, they won't gunk up the fabric like peanut butter does.
- The Texture Test: If your dog is older and has dental issues, soak a piece in water for thirty seconds. it rehydrates into a soft, meaty morsel that’s easy on the gums.
Stewart has stayed relevant because they didn't try to get fancy. They stuck to a single process that preserves the integrity of the meat. In a world of "dog jerky" made with sugar and "dental chews" made with starch, a bucket of dried liver is surprisingly honest. It’s not the cheapest treat on the shelf, but when you look at the nutritional density and the reaction you get from your dog, the value is pretty obvious. Stick to the single-ingredient options, keep the lid tight, and use the dust as a topper. Your dog will think you finally learned how to cook.
