In today’s world of dog food, protein is king, but are there times when too much protein can have ill effects? The answer is complicated, but yes, in a few instances, low protein diets may benefit your dog’s health. In this article, we will discuss the whys, the when, the how, and the best low protein dog foods.
As discussed, so many times before, there is a mind-blowing number of dog food options available, which can make choosing the right food for your pup challenging. And I think we can all agree that we just want what’s best for our dogs. So, with that in mind, the list of foods below is chosen for a variety of reasons, like:
- Availability – You will always be able to find the foods either at Amazon or Chewy.
- Price – We do our best to include a range of price points.
- Special Dietary Needs Beyond the Main Subject of the Article – Though not every situation can be covered we do our best to cover more common issues such as food sensitivities or joint disease.
However, before we jump in, it is critical to state that low protein dog foods should only be used when advised and supervised by your trusted veterinarian. Protein is an essential macronutrient in your dog’s diet. Switching your dog’s diet to a food low in protein can have severe adverse health effects on your dog.
Changing your dog to a lower protein diet will not cure liver or kidney disease, but it may help slow the progression.

Why Your Dog May Benefit from a Low Protein Diet
There are just a couple of situations in which a dog food with low protein would benefit your dog’s health. Dogs with chronic illnesses such as kidney or liver disease may require a lower protein diet to maintain a healthy lifestyle. If you and your vet determine that a low protein food is the right choice for your dog, you will want to follow up with them regularly for bloodwork to ensure the food is having its desired effects and not causing other issues.
The other reason you may consider a dog food lower in protein would be if your dog is at a higher risk or is predisposed to kidney or liver disease. Again, before switching your dog’s food, take the time to consult a professional.
Dogs with chronic kidney disease (CKD) benefit from lower protein diets because decreased protein can slow the progression of CKD through lessening the stress of expelling protein waste through the kidneys. According to the VCA, the recommended amount of protein in dry dog food, “…for dogs with CKD is less than or equal to 14-20%.”
According to Tufts University, dogs with chronic liver disease should only be changed to a low protein diet if the dog has gone into liver failure and can no longer break down proteins. Liver failure occurs if the liver function decreases to around 70% of its normal working capacity, and your dog is suffering from Hepatic Encephalopathy. The other reason veterinarians recommend changing a dog’s diet due to liver disease is due to copper build up in the liver, a genetic condition.
Dogs with less severe liver disease may benefit from dog food that is lower in protein and supports good digestive health. Depending on the severity of the liver disease, your vet will recommend the proper protein range for your dog.
It is necessary to mention that there is a difference between a lower protein diet and a low protein diet for dogs. A real low protein diet will consist of prescription food that has been approved to contain a severely limited amount of protein. The Association of American Feed Control Officials (AAFCO) recommends and 18% minimum protein level for a balanced diet. In contrast, a lower protein diet consists of food that does not require a prescription and contains around 18% protein. Keep in mind most dog foods average well above the 18% minimum level.
How to Choose a Low Protein Dog Food
After deciding with your vet that your dog should change their diet, they will give you a protein percentage range to look for when choosing a dog food. Taking that into consideration, you will likely have other factors to consider as well, such as:
- If your dog has other health issues such as food allergies or arthritis
- Dog’s weight
- Dog’s energy level
- Taste – Whether your dog will eat the food or not
- Ease of availability
- Price
- Quality
- Where the ingredients are sourced
- Where the food is manufactured
- Ingredients

Conclusion
Low protein foods aren’t near as common as high-protein diets, but they are definitely needed.

Though these foods won’t cure our dogs, they can make a significant impact on their quality of life.
Hello,
Do you know much about Canidae senior? My dog has liver and kidney disease and I’m looking for a low protein food. He’s always been on canidae pure but I’m wondering if you’ve reviewed the senior line.
Hello Isabelle!
Thank you for reaching out, I am sorry to hear your dog has kidney disease. Changing food is the best way to help support him with this new diagnosis.
I did review them in a different article regarding senior diets. https://k9deb.com/best-senior-dog-foods/#13_CANIDAE_PURE_Limited_Ingredient_Senior_Dog_Food
It is part of their Canidae pure line, so would likely be easy to transition your pup to. Unfortunately, though the senior variety is not low in protein, it has a CRUDE PROTEIN 28.00% min.
So maybe switching brands to a lower protein option might work best.
Hope this helps! Hope your dog is doing better!

My mini pin also has liver and kidney issues and she is 14 yrs old. I was told low protein and not grain free.
What foods dry and wet would you recommend.
Claudean,
Have you tried KD? It is a prescription diet you can get through Chewy. It comes in both wet and dry formulas and two different protein options, beef, and chicken. Purina also has a prescription diet that may work for your dog; NF also available through Chewy.
You may also want to ask your vet about Denamirin; it is a supplement for dogs with liver disease.
Jessica
My dog might have Cushing disease. I make her dog food with ground turkey, yams, or pumpkin, or potato. Organic beans, spinach, carrots, zuchinni. Shes allergic to chicken, rice, and peas. Do you know about a dry dog food that is more holistic, organic, and doesn’t have chicken , peas, and rice and is low is protein. I wanted to supplement a little bit because its so costly, but I dont want to give up on feeding her more healthier natural foods.
