Buyer’s Guide: How to Choose the Best Dog Foods for Kidney Disease

What Do Dogs with Kidney Disease Need Nutritionally?

Dogs who experience some level of kidney failure have different nutritional needs than healthy dogs. Because the kidneys are responsible for extracting and passing waste from digestion, particular food and nutrient profiles put more stress on the kidneys, which can be harmful when the kidneys are already struggling to function correctly. Changing the concentrations of the macronutrients, vitamins, and minerals your dog consumes can help preserve their kidney function for as long as possible.

Here are the nutritional keys to feeding a dog with kidney failure:

Low Protein

While lowering the protein content of a dog’s diet is a highly controversial subject, there’s no doubt that a high protein diet puts an undue amount of stress on the kidneys. Some vets may suggest a low-protein content diet to preserve your dog’s kidney function for as long as possible to remove some of the pressure on the kidneys.

The protein content of dog food has long been a source of contention amongst dog owners and veterinarians alike. However, when left to their own devices in observation, dogs gravitate to an omnivorous diet rather than a strictly carnivorous diet. So, with proper care, transitioning a dog to a lower-protein diet should not be harmful to them.

Low Sodium

Sodium is another mineral that puts extreme stress on the kidneys when being processed. Sodium is not only bad for the kidneys; it’s bad for dogs in general. High sodium levels in the bloodstream can make dogs ill and even be fatal.

While it’s unlikely that your dog will be able to kill themselves simply by eating salty foods, doing so puts a lot of pressure on the kidneys, and if your dog’s kidneys are already struggling, this could be the end of their kidney function.

Low Phosphorus

Extremely high phosphorus concentrations in food can be dangerous already since phosphorus can lower bone density. However, phosphorus is also highly stressful for the kidneys to process. So, reducing the phosphorus content of your dog’s food will help preserve their kidney function for as long as possible.

Boosted Omega-3 Fatty Acids

Omega-3 Fatty Acids have been shown to bolster kidney function and offer improved kidney support whether your dog has trouble with their kidneys or not. They’re a great addition to any diet, but dogs with kidney troubles need even more omega-3 fatty acids than the average dog to help slow the progression of their kidney disease.

Moisture

Moisture is another critical part of treating kidney disease. Acute kidney failure is usually treated with intravenous fluids to help dilute the toxins in the kidneys and take the stress off them to prevent their kidneys from further damage.

Increasing the amount of moisture in your dog’s diet will help keep their kidneys functioning for longer. It’s crucial to always keep fresh water available for your dog since they will likely have an increased thirst due to the disease. You can also help increase the moisture in their diet by feeding them canned food and adding water to their kibble.

Dehydrated foods are an excellent option for dogs who need more moisture in their diets since you can control the humidity added to them, and you can add more water when rehydrating the food if your dog will tolerate it!
