Understanding Dog Kidney Disease and How Diet Can Help

December 27, 2025

Kidney disease is one of the more common health issues affecting older dogs. In fact, veterinarians estimate that as many as 1 in 10 dogs will experience some form of kidney disease in their lifetime, with cases increasing as dogs age (roughly 30% of dogs over 10 years old).

Several factors can increase a dog’s risk of developing kidney disease. Age is the biggest factor, but dental disease, infections, kidney stones, obesity, high blood pressure, and certain hereditary conditions also play a role. Importantly, kidney disease and diabetes are often interconnected. When the kidneys are not functioning optimally, the body struggles to regulate electrolytes, hormones, and blood sugar. Over time, this imbalance can put extra strain on the pancreas and increase the likelihood of developing diabetes.

While a canine kidney disease diagnosis can feel overwhelming, there’s a lot you can do to support your dog’s comfort and long-term health.

Common Symptoms of Kidney Disease in Dogs

Symptoms of dog kidney disease appear slowly and can be easy to miss at first. If you’re noticing changes in your dog’s behavior or habits, trust your instincts and talk to your vet. Early detection makes a big difference. Some of the most common signs include:

Increased thirst or urination
Loss of appetite
Unexplained weight loss
Lethargy or lower energy levels
Nausea or vomiting
Bad breath (often “ammonia-like”)

Caring for a Dog with Chronic Kidney Disease

While chronic kidney disease or chronic renal failure (CRF) cannot be cured, giving your dog the right care can help manage the condition and greatly improve their quality of life. Many dogs continue to live happy, comfortable years with the right routine.

Here are a few tips to help support your dog:

Keep fresh water available at all times.
Follow your vet’s recommended diet, often lower in phosphorus and moderate amounts of quality proteins that are easier to digest. Stick with all natural, unprocessed foods.
Offer smaller, more frequent meals.
Monitor weight, appetite, and water intake.
Keep regular vet checkups to track progression.
Provide gentle exercise to support mobility.

The Role Nutrition Plays in Kidney Disease

Diet plays a big role in managing kidney health, especially given the close link between chronic kidney disease and diabetes. Dogs with either condition often benefit from diets that support:

Healthy digestion
Balanced blood sugar
Inflammation management
Proper hydration
A strong immune system

Healthy dog treat selection matters too. Avoid foods or treats that are high in sugar or sodium, such as processed meats, broths, cheese, and snacks with artificial preservatives or fillers. These ingredients can place unnecessary stress on both the kidneys and the pancreas.

How Old Dog Diabetic Dog Treats Support Kidney Health

Even though our treats are formulated for diabetic dogs, the carefully selected, natural ingredients serve as gentle, low-glycemic snacks for dogs with kidney disease and support healthy pancreatic function. Made with herbs used for centuries for their wellness benefits, these treats contain no added sugars, preservatives, or artificial flavors—just wholesome, nutrient-rich ingredients.

Here’s how our ingredients support kidney health:

Dandelion Root – Supports digestion, naturally helps reduce excess sugar in the blood, and may act as a gentle detoxifier for kidney function.
Kelp – Rich in Omega-3s, iodine, and minerals that support thyroid function and overall wellness. A healthy metabolism supports kidney and pancreatic balance.
Pumpkin – A nourishing source of vitamin A and fiber. Pumpkin is gentle on digestion and often recommended for dogs on restrictive diets.

Pure Unsweetened Applesauce – Apples contain pectin, which helps regulate blood sugar and strengthen the immune system, especially important when kidney function is compromised.
