Understanding Kidney Disease In Dogs

The kidneys are responsible for filtering waste products out of your dog’s blood and they also play a role in maintain fluid balance in the body.

When the kidneys become damaged or lose their ability to function properly, it can lead to some serious problems.

Kidney disease can be caused by a wide variety of things including genetics, trauma, ingesting toxins, and infections.

Chronic kidney disease takes time to develop and doesn’t always show outward signs.

When those signs do show up, however, you need to take your dog to the vet for treatment and you may also need to change what you feed your dog to support its kidneys.

Here are some things to look for in a dog food for kidney disease:

  • Quality Ingredients. Because your dog’s kidneys are damaged, their ability to filter out toxins may be impaired which means that high-quality ingredients are even more important.
  • Low Protein. A low-to-moderate protein content is recommended for dogs with kidney disease – something in the range of 13% to 18%.
  • Omega Fatty Acids. There is some evidence to suggest that omega-3 fatty acids may benefits dogs with kidney disease – they also provide support for healthy skin and coat.
  • Moist Food. The kidneys need water to function properly, so choose a dog food that is high in moisture – that might be a wet food, moist food, or rehydrated dry food.

Keeping all of these things in mind, you’re now ready to learn how to choose the best dog food for kidney disease. Here’s what you need to know:

How To Choose The Best Dog Food For Kidney Disease?

The most important nutrients for dogs are protein and fat. Protein helps your dog maintain lean muscle mass while fat provides a concentrated source of energy.

Generally speaking, dogs need 18% protein in their diet but dogs with kidney problems need lower protein – between 13% and 18%.

Fat should be somewhere around 10% to 15%, depending on the dog’s activity level.

Dogs don’t have specific requirements for carbohydrates, but these nutrients can provide fiber, energy, and vitamins and minerals.

Look for digestible sources like whole grains, vegetables, beans, and legumes. And make sure your dog’s food contains fiber for digestion as well.

In addition to these nutrients, your dog can also benefit from certain supplements in its diet.

Fresh fruits and vegetables provide natural sources of vitamins and minerals that are easy to digest.

Chelated minerals are bound to protein molecules to increase absorption. Prebiotic fibers and probiotics support healthy and regular digestion.
