Why Single-Ingredient, Freeze-Dried Treats Matter

  • Easier on sensitive stomachs — Fewer ingredients reduce the risk of digestive issues or allergies.
  • Nothing hidden — One ingredient means no fillers, no by-products, no mystery additives.
  • Minimally processed — Freeze-drying preserves nutrients without high heat or artificial preservatives.
  • Better taste — Locking in natural flavor makes them highly appealing — even for picky eaters.
  • Premium quality — Every ingredient meets the same safety and quality standards as food made for people.
  • Confidence you can feel good about — You know exactly what you’re feeding your dog, every time.

Why Muscle Meats

Just like humans need daily vitamins and minerals to stay healthy, dogs need real muscle meats — organ meats and heart muscles packed with naturally occurring taurine, CoQ10, iron, and B vitamins that kibble alone can’t provide. Each of our three treats targets different aspects of your dog's health.

🦬 Bison Liver — Immune · Coat · Skin

🐔 Chicken Heart — Heart · Muscle · Energy

🐄 Beef Heart — Joints · Mobility · Digestion

"Most dog owners assume treats are healthy — but many pet parents don't actually know what's inside the typical options lining store shelves. That's why K9 Krunch keeps things simple and transparent."

More FAQs

Is beef heart an organ meat or a muscle meat?

Beef heart is technically classified as a muscle meat, not an organ meat, because it's made of cardiac muscle tissue. That's an important distinction: unlike liver, kidney, or spleen, beef heart can be fed daily without the vitamin A loading concern that comes with true organ meats. It's lean, nutrient-dense, and built for regular feeding.

What is CoQ10 and why is it in beef heart?

CoQ10 (Coenzyme Q10) is a naturally occurring compound that supports cellular energy and cardiovascular function. Heart muscle — including beef heart — is one of the more concentrated natural sources of CoQ10 in the diet. For aging dogs, active dogs, and working breeds, that supports joint mobility, sustained energy, and heart health.

My dog has a sensitive stomach. Is beef heart easier to digest than other beef treats?

Often, yes. Many "beef" treats contain beef meal, by-products, or beef blended with grains, glycerin, or preservatives — any of which can trigger digestive flare-ups. K9 Krunch Beef Heart is a single ingredient: USDA-sourced beef heart. Customers regularly tell us their sensitive-stomach dogs handle it far better than mixed beef products.

Is beef heart suitable for senior dogs?

It's one of our most recommended proteins for seniors. The 65% protein content helps maintain lean muscle mass that naturally declines with age, the CoQ10 supports joint and heart function, and the single-ingredient profile is gentle on aging digestive systems. Start with the lower end of the feeding guide and adjust based on appetite and activity level.

Why is the protein content so high (65%)?

Because beef heart is protein. There's no flour, glycerin, starch, or filler in the bag — and freeze-drying removes the water, which concentrates what remains. Most commercial treats show lower protein percentages because the majority of the bag isn't actually meat.

These are Layla’s most high value treats. She knows where they are and wants them for dessert.

At first my pup just danced around these treats, you know what I mean! But once he got over it he eats them every day.

I love that it is a single ingredient healthy treat!

Lifesaver for my senior lab

My 11-year-old yellow lab has been slowing down for the last year. Started giving him beef heart for the CoQ10 about 6 months ago and his energy is noticeably better. Goes for full walks again. I won't claim causation but the timing is hard to argue with.

Joint support I can actually see working

Switched my 8-year-old shepherd from a joint supplement to daily beef heart treats. Same vet, same dog, dramatically better mobility scores at her last check-up. Plus she actually wants these — she'd spit out the supplement chews half the time.

CoQ10 in a treat? Yes please

I'm a vet and these come up in conversations with senior dog owners constantly. Beef heart is one of the few real-food sources of CoQ10 that's also palatable enough to be a treat. K9 Krunch's sourcing is clean and traceable, which matters for what I recommend.

Daily feeder for my active aussie

My Australian Shepherd runs hard 7 days a week — agility, hiking, herding. He needs sustained protein and beef heart is the densest single-ingredient treat I've found. 65% protein. Daily reward and I see no decline in his coat or energy. Highly recommend.

Cleanest ingredient list I've found

I've been on a years-long mission to find treats with no garbage in them. K9 Krunch is the first brand where I read the back of the bag and didn't find a single thing I had to look up. One ingredient. That's it. Refreshing.

Firm stools, happy dog

Switched to beef heart from a generic chicken-based treat and my dog's digestion is visibly better. Firm stools, no gas, no mid-night stomach gurgles. Sometimes the best signs of a good treat are the boring ones.

Larger pieces than expected, good value

Pieces are bigger than the chicken hearts, which is great for my Great Dane — bite-sized for him is fist-sized for a chihuahua. I break each in two for training but for casual rewards they're perfect. Solid value if you have a big breed.

Great for big breeds, smells a bit strong

Mastiff loves these and the size suits him well. Smell is stronger than the bison liver, which is saying something. Not a deal-breaker but worth knowing if you're sensitive. Keeping in rotation.

Quality is there, packaging could be better

Treats themselves are excellent. Re-seal on the bag is just okay though — I transferred them to an airtight container after the first week. Other than that, no complaints. Dog devours them, ingredients are clean, ships fast.

Solid alternative to liver, less rich

I rotate beef heart and bison liver for my dog. The heart is a bit less rich which I prefer for daily — liver every day felt like too much. Heart works well as a base treat for training and the protein content is genuinely impressive.
