The short answer: you make kidney-friendly dog treats by baking a few low-phosphorus, low-protein, dog-safe ingredients—think pumpkin puree, egg whites, low-sodium homemade broth, and rice flour—into simple biscuits. Kidney (renal) diets work by easing the load on the kidneys, so the goal is to keep phosphorus and excess protein down while keeping the treat tasty. Always clear any new treat with your vet first, especially if your dog has diagnosed kidney disease. Here's the recipe we trust, plus why each ingredient earns its spot.
Why do kidney dogs need special treats?
When a dog's kidneys aren't filtering the way they should, waste products from protein and minerals like phosphorus build up in the blood. That's why veterinary renal diets are built around lower phosphorus, moderate high-quality protein, and good hydration. The American Kennel Club notes that dietary management is one of the most important tools for dogs living with chronic kidney disease (AKC). Standard grocery-store biscuits are often loaded with phosphorus and salt, so a homemade treat lets you control exactly what goes in.
What ingredients are kidney-friendly?
These four do the heavy lifting in our recipe:
- Pumpkin puree — low in phosphorus, high in fiber, and gentle on digestion. Use plain canned pumpkin, not pie filling.
- Egg whites — a high-quality, lower-phosphorus protein source that's easier on the kidneys than most meats.
- Homemade low-sodium chicken broth — adds flavor and moisture without the sodium of store-bought broth.
- Rice flour — a wheat-free flour that's easy on the stomach and low in phosphorus.
VCA Animal Hospitals emphasizes that phosphorus restriction is central to slowing kidney disease progression, which is why these low-phosphorus swaps matter (VCA).
How do you make DIY kidney dog treats?
- Mix the dough. Combine 1 cup rice flour, 1/2 cup pumpkin puree, 2 egg whites, and 1/4 cup homemade low-sodium chicken broth until it forms a dough.
- Shape the treats. Roll the dough out and cut it into small shapes with a cookie cutter.
- Bake. Place on a parchment-lined sheet and bake at 350°F for about 25 minutes, or until crisp.
- Cool and store. Let them cool completely, then keep them in an airtight container in the fridge.
How should you store them and how many are safe?
Because these treats have no preservatives, store them in an airtight container in the refrigerator for up to a week, or freeze for longer. Treats of any kind should stay under about 10% of your dog's daily calories—the ASPCA and most vets recommend keeping treats to that ceiling so the balanced diet still does the work (ASPCA). For a kidney dog, moderation matters even more, so check the portion with your vet.
What about single-ingredient chews for sensitive dogs?
Baked biscuits are great, but some dogs on managed diets also do well with simple, single-ingredient chews—no fillers, no mystery additives, just one real thing. At Bully Sticks Central, our chews are 100% natural, 100% real meat, fully digestible, and contain no rawhide, ethically sourced from grass-fed American and Argentinean farms. That said, many meat-based chews are higher in phosphorus and protein, so they are not automatically appropriate for a kidney dog. If you're weighing lighter options, our guide to whether trachea chews are safe walks through what to look at, and you can always ask your vet before adding any chew to a renal diet. For a fun, lower-phosphorus homemade option, a dab of xylitol-free peanut butter can work in moderation—again, vet's call first.
Should you talk to your vet first?
Yes—every time. Kidney disease has stages, and the right phosphorus and protein targets depend on where your dog is. The recipe above is a starting point, not a prescription. Your veterinarian can tell you whether these treats fit your dog's specific diet and how many are okay. As founder of Bully Sticks Central, my honest take is simple: homemade treats give you control over ingredients, but a vet gives you the guardrails. Use both.
Frequently asked questions
Can dogs with kidney disease eat treats at all?
Usually yes, in moderation, as long as the treats are low in phosphorus and sodium and your vet approves. Keep treats under about 10% of daily calories.
Is peanut butter safe for kidney dogs?
Plain, xylitol-free peanut butter can be given in small amounts, but it does contain phosphorus and fat, so check the portion with your vet before using it as a treat.
Are store-bought dog treats bad for kidney dogs?
Many are high in phosphorus and salt, which is why homemade or vet-recommended renal treats are often the safer choice for dogs with kidney disease.
