Be Careful with Feeding Tuna to Dogs with Kidney Disease

Canned Tuna

Dogs that suffer from chronic health conditions like kidney disease will require a strict dietary change in order to maintain their health. For example, some studies have shown that pets with kidney disease-specific diets may live twice as long as those that eat a regular diet.

One common question that dog owners have is whether it is safe to feed tuna to dogs with kidney disease. Ideally, a diet oriented for dogs with chronic kidney disease should see a reduced intake of protein, phosphorus, and sodium, while seeing an increased intake of dietary omega-3 fatty acids.

Tuna indeed is an excellent source of omega-3 fatty acids but it’s also packed with protein. Canned tuna is also likely to be packed with sodium, especially if it is stored in brine. Our recommendation is to find your dog an alternative source for omega-3 fatty acids unless your vet has made specific recommendations for your dog’s diet.

With tuna, you also need to worry about the possibility of mercury poisoning with tuna known for having one of the highest amount of mercury among edible fish species.
