Buyer’s Guide: Picking the Best Low-Protein Dog Food

When it comes to shopping for appropriate dog food, your choices may seem overwhelming, especially for a low-protein diet. Not all dogs require a low-protein diet, and we recommend checking with a veterinarian to ensure it’s warranted before switching. That said, let’s dive deeper into what to look for in a low-protein diet for your dog and address any questions you may have.

Why Would a Dog Require a Low-Protein Diet?

Certain medical conditions may cause your dog to require a low-protein diet. Oftentimes, the reasons are due to kidney disease, liver disease, or some types of bladder stones, which is the least common reason. The purpose of feeding a low-protein diet is to ease the stress and workload of the kidneys and liver when disease is present. Also, if disease is present, a low-protein diet will often be permanent.

While some dog foods listed in this article do not require a prescription, it’s important to get the go-ahead from a vet before putting your dog on one, and most times, the diet will be by prescription only to ensure the food is indeed suitable for your dog’s particular condition.

What Exactly Is a Low Protein Diet?

The general consensus is that a low-protein diet should contain 20% or less protein. Some low-protein diets may have slightly higher protein percentages, but you’ll find that most veterinary dog foods formulated by veterinarians will usually have well below 20%, with percentages averaging anywhere from 3% to 12% protein content.

There are some non-veterinary formulas that are lower in protein for dogs that need weight management or senior dogs that are less active and not able to burn calories like they once did in their prime—this is another reason to ensure your dog requires a true low protein diet rather than switching your dog to this type of diet on your own.

Things to Consider When Looking for a Low-Protein Dog Food

Protein Percentage

A low-protein diet should not exceed 25% protein, and ideally, that number should be lower than 20%, with a range of 3% to 20%. The food should also have a lower fat content, not to exceed 12%.

Complete and Balanced

In addition to a low protein percentage, dog food should consist of a well-balanced diet that contains essential antioxidants, omega-3 fatty acids, carbohydrates, fiber, vitamins, and minerals. Dogs with sensitive digestive systems will require a formula with prebiotics and probiotics for smooth digestion. Omega fatty acids, such as fish oil and canola oil, will help keep your dog’s skin and coat healthy and shiny.

Another important factor to look for is to ensure the dog food is approved by the Association of American Feed Control Officials (AAFCO), which will ensure the dog food is complete and balanced.

Phosphorus Content

If a low protein diet is needed due to liver or kidney issues, then the phosphorus content will play a huge role in the diet. Studies indicate that phosphorus has more of a significant impact on the organs rather than protein, and too much phosphorus can be dangerous to your dog. Dogs with kidney issues will not be able to filter phosphorus very well, which is why it’s important to check with your veterinarian before switching your dog to a low-protein diet to ensure the phosphorus content is not too high.

Quality Over Quantity

One issue you may run into is the price of high-quality dog food that’s low in protein, which will be more on the pricey side compared to regular dog food diets. However, it’s vital to provide your dog with all essential ingredients while feeding a low-protein diet, which is where your veterinarian comes in—your vet can help you in making the appropriate decision on which diet is best for your dog’s particular condition.

A high-quality dog food will have real meat as the first ingredient rather than a by-product meal or rice. If the dog food contains meat of low quality, then your dog will not receive the essential amino acids required to stay healthy while on a low-protein diet.
