What Are Low Protein Dog Foods?

Low protein dog foods are dog foods with a lower concentration of protein and a higher ratio of carbohydrates and fats. For instance, most commercial pet foods contain an average of 25% protein, whereas low-protein versions contain approximately 10-12%.

They are not ideal for all dogs, and that is why their use is advised for dogs with specific ailments like:

  • canine pancreatitis,
  • kidney stones,
  • urinary problems,
  • liver disease, or
  • kidney disease.

Under such circumstances, it can be very helpful to support the effective treatment of the ailment to combat.

When Should I Give My Dog Low Protein Dog Food?

We have already seen some circumstances that require a switch from the normal protein ratio to lower alternatives, but to understand it properly, here you have a full explanation.

Kidney Disease

By far, it is the most common reason why your veterinarian can suggest you feed your dog a low protein diet because the kidney metabolizes protein, and by reducing the ingest, the workload of the organ is also reduced, which is essential in cases of Chronic Kidney Disease (CKD), because it will increase the chances of survival.

The kidneys of your dog will need extra help to get rid of elements like phosphorous, nitrogen and creatinine, which when in high concentrations, can create electrolyte disturbances that are especially harmful t animals that suffer this condition. By feeding your dog a lower ratio of protein, but of higher quality, your pet will have an easier time flushing out these minerals.

Furthermore, it is worth noting that, in the vast majority of cases, your veterinarian will recommend moist food over dry food, because the first is much easier to digest and process.

bioavailability of dog food
Nutrients such as proteins, fats, carbs, and vitamins get digested by dogs, but not all of each one will be used. Raw feeding and premium dog foods have better bioavailability than cheap foods.

Kidney Stones

Another common cause for feeding your dog a low protein diet is to eliminate kidney stones. Unlike CKD, the diet will be temporary until your pet has gotten rid of all the renal stones. However, it is important to remember that a high-protein diet is not an inherent cause of this abnormality, but reducing the protein ratio helps with the treatment (see study).

Liver Disease

Similar to CKD, when your dog suffers from liver disease, it is essential to reduce the workload of the organ affected. Such foods will contain protein of higher quality and easier digestibility, to bring the body of your dog more resources to heal properly because it is essential to retain muscle mass during the process. Although, you need to follow the instructions of your veterinarian carefully.

The quality of protein plays a very important role in low-protein food because you want to give your pet an easy time digesting it, and therefore, protein from animal sources will always be superior to plant-based such as rice, corn, wheat, etc.


Another common reason why owners opt for this kind of diet is due to hyperactivity; however, it is more a problem of the source rather than the ratio of protein in the dog food, because as long as the protein is high quality and easily digestible, it should not interfere with the behavior of your dog.

Is A High Protein Diet Bad For My Dog?

It entirely depends on the context. Indeed, it is not the same for a healthy and active dog than for an old dog with chronic kidney disease. Therefore, here you have the pros and cons.

Pros of a Low-Protein Diet

  • Ideal for puppies to develop and grow optimally
  • Perfect for pregnant mother dogs (critical for their optimal development)
  • Better digestibility
  • Allows your dog to retain its muscle mass and shed off extra fat (source)
  • Controls the appetite of your dog by making it feel more satiated after a meal

Cons of a Low-Protein Diet

  • It can lead to weight gain (because many high protein dog foods contain low-quality protein sources that are also very high in calories). It is a serious issue because 59% of dogs in the U.S are obese!
  • May be problematic for dogs with severe cases of kidney disease and liver disease, especially if the quality of protein is low (ex: rice, corn, and wheat). Therefore, it is important to lower the ratio and increase the quality (meat based; lamb, chicken, fish, etc.)

What To Consider When Buying Low Protein Dog Food

Do you want to know if a low-protein dog food is a good choice? In case you want to judge the plethora of low protein kibbles available, make sure you are using the below criteria. The amount of protein contained is obviously a must-know…


Always read the list of ingredients because the quality is better than quantity, especially when we are talking about a low protein ratio. As your dog will get less protein, it needs to be of higher quality to retain their muscle mass and guarantee optimal health.

Easy to digest and assimilate. Furthermore, you should also check the quality of the fats and carbohydrates they include, along with the additives and possible fillers (avoid them at all cost).

Phosphorus Level

Another metric to look for is the phosphorus level because high levels of it can be problematic for dogs with specific conditions like heart disease, kidney disease, and liver disease. Nonetheless, you should check that your pick of low protein food for dogs also includes B-complex vitamins, omega 3 (like fish oil), antioxidants, and amino acids because they are essential to counteract the low levels of phosphorus.

This is one of the most important metrics, even as important as the protein ratio because it has been proven to slow the progression of renal failure.

Age Appropriateness

Age plays another determining role. Always check that the formula is appropriate for your dog because it would be a mistake to give your puppy a dog food like Royal Canin Veterinary Diet, which is formulated for senior dogs. In addition, in the case of puppies, they need a higher protein ratio to ensure their optimal development.

Furthermore, always check out the list of ingredients, to ensure that it does not contain elements that could trigger reactions in your dog.


You should always pick a flavor that your dog likes, so he can switch to it easily and avoid potential digestive issues. If your dog loves lamb, then it makes sense to pick a food like Premium Edge Lamb, Rice and Vegetables Dry Dog Food that uses it as its main animal protein source.

Furthermore, it is always worth it to read reviews about the flavor, especially from owners with picky dogs because it will give you a clear idea if your dog will like it or not.


Again, another reason why checking the list of ingredients is fundamental because you need to ensure that it contains all the elements that your dog needs for its treatment. In addition, you need to ensure that all of the macronutrients are of the highest quality, to bring your dog balanced and complete nutrition.

Things to Remember

Finally, it is worth it to remember the following things when buying food for dogs with low protein, to ensure that you pick the best for your pet.

Spayed and Neutered Dogs

Spayed and neutered dogs are prone to weight gain due to their increase in appetite and lack of activity. Therefore, it is preferred to opt for a higher protein ratio (to satiate them) and to pick a food that helps with weight management, such as Holistic Select Natural Dry Dog Food, to control their weight.

Breeds Predisposed To Allergies

Breeds like Cocker Spaniels, Dalmatians and Lhasa Apsos might be allergic to some ingredients in low-protein dog food (like soy, corn, and wheat), therefore, double-check the list of ingredients. Some goods options in the market are Blue Buffalo Basics Limited Ingredient Diet and Natural Balance Limited Ingredient Diets.

Pregnant and Lactating Dogs

As stated before, pregnant and lactating mother dogs have higher nutritional requirements than low-protein dog food may not be able to supply them with. Therefore, it is better to opt for a normal protein ratio diet. The same goes for puppies. In conclusion, it’d be a bad idea to feed your pet a low protein or low-fat diet during this stage.

Environmental Conditions

It is also important to factor in environmental conditions because if your dog lives in the cold and has to work on a daily basis – like a Husky in Alaska – then you need to upper up his protein supply, along with the total caloric content because your pet will need plenty of energy. The same goes for feeding athletic dogs.

Therefore, as you can see, there is no inherent problem with a high-protein diet, as long as the quality of the protein is exceptional. Nonetheless, in specific cases like CKD and liver disease, as well as kidney stones, low-protein dog food can be a better choice.

In conclusion, it is not all black and white, because like a low-protein diet has its benefits, the same goes for a low-carb diet. It all depends on the context.
