Dogs require high-protein diets. However, there are instances when a reduction in the usual amount of proteins in a dog’s diet is required. Dogs that are sick with a certain condition can benefit more from a low protein dog food than if it were to stick to the usual high protein diet. As such if your dog has a health condition that warrants the giving of low protein foods, then you really have to provide your pet with only the best. Our team searched far and wide to bring to you 8 of the best low-protein dog foods.

After quite a bit of research, we landed on Hill’s Science Diet for our pups. We just recently had to switch to the Adult 7+ and the pups still like it just as much (which we were worried about) It gets wonderful reviews and it’s vet-approved so we’re all in. Chewy is also one of the best companies we’ve worked with. The food arrived one ONE day – such great service.

My doggies have lost weight and their coats are so much shinier! I do not measure food for my 7 dogs (impossible) just leave it out all of the time. They are still slimming up! The main porky one has lost 12 pounds. Took a few months, but yay! I use the same in the canned version for a treat in the morning. One doggy gets pills so I just put a ball of the canned and press it onto the pills. She gobbles it up! The rest get 5 balls each. I have been won over by Blue Buffalo! I use Autoship and it is so nice to have this delivered to my door. Took a little while to figure out how often and how much for the autoship but I have a few extra bags as a backup. Better to have extra than run out. The schedule has now worked out great!

Excellent for our overweight Golden Retriever service dog. He has a very sensitive stomach, and can easily have diarrhea. I tried all brands before finding Holistic Select and getting diarrhea under control. But he was gaining weight on Holistic’s Large Breed kibble, so I switched to weight management. Thank goodness this formula also produces a firm stool and is great for a sensitive stomach. He isn’t losing weight fast, but it is coming off.

I have 4 dogs eating this food, two have always been picky and needed human food mixed in their food to get them to eat and when the human food was gone, they quit eating and left whatever in their dishes. This food means no human food is needed and they empty their dishes. They sometimes skip meals (mostly breakfast) but they are no longer as picky and skip fewer meals than before we started Ultra. This food is a keeper. Another one is overweight, but because everyone likes Ultra Weight Management, they all get it. This helps all of them stay healthy and full of energy.

Rose was diagnosed with a chicken allergy in November. (We thought it was just grains, poor girl) So first we tried a fish-based food in her previous brand. Itching and chewing went down slightly. After we finished that bag, I went looking for other “alternate proteins” our vet recommended, but at a decent price. Found Natual Balance and went with the bison formula. Wow, we’ve been using it about a month now and the chewing and licking are way down. We switched to cold turkey so there would be no contamination with the previous food. Rose LOVES it and she’s doing great. Even her poops are firmer (because of the grain issues, we’ve had trouble getting enough fiber into her). I think she’ll always chew and lick a little bit, but now it’s very manageable Natural Balance has a great formula for us and it doesn’t break the bank.

I was very disheartened when my 13-year-old rat terrier was recently diagnosed with kidney failure. My vet told informed me that I needed to change his entire diet and that Pepper could no longer have his favorite treats. I searched the internet for treats he could have and I bought two different kinds, one being Mattie’s Treats. Pepper loves these treats! He didn’t like the other kind I purchased at all and has basically refused to eat them. He really likes these and they even work well in his Kong toy, which is one of his favorite past times. Thank you so much for thinking of dogs with kidney disease and for making these wonderful treats!!

My Dachshund had surgery to remove about 1/8 cup of stones from her bladder when she was about 6 years old. She is a mini, so that was a huge amount for a tiny dog. She almost died, and the vet recommended food that would help keep her bladder free of stones. This food has worked for her for several years, and being able to have it delivered was a real Godsend since the nearest source of the food was 50 miles away. Having this on auto-ship has made my life easier for both me and my two doxies (both have kidney issues, but only one has had surgery). I LOVE auto-ship

Our doodle began having stomach issues. We did every test under the sun and our vet couldn’t figure it out. Eventually, we learned she had developed allergies to all kinds of foods (chicken, peanut butter, etc). By the time we figured it out, she had lost almost 10lbs. We tried this food and almost instantly she began to improve. 3 months later and her weight is back on. She’s healthy, happy, and her coat looks great. Highly recommended for dogs with allergies and sensitivities to lots of stuff!

Best Low-Protein Dog Food: Buyer’s Guide

Going for the best low-protein dog food in the market can be exceptionally difficult since most pet parents are not even sure when can a dog food be considered “low-protein”. To help you understand this unique nutritional requirement of certain dogs, we’ve dedicated this section to answering some of the most common questions that pet parents have about low protein dog foods and how you can choose the best one for your beloved pet.

Why Do Dogs Need a Low Protein Diet?

As we have mentioned at the beginning of this article, dogs – or any organism for that matter – need proteins to help build, grow, and develop cells and tissues, synthesize hormones and enzymes as well as other substances of physiologic importance, and contribute to the overall development of the organism. Proteins, like all other nutrients and substances that enter the dog’s body, have to be processed by a variety of organs but mostly the small intestines, the liver, and the kidneys.

The small intestines are where proteins in food are digested and broken down into their component amino acids to be absorbed into the dog’s blood. The liver is the organ that processes the many byproducts of protein metabolism. The kidneys are what eliminate nitrogenous wastes and other substances so that the body will not be filled with these unnecessary molecules. It can thus be understood that any problem that may arise in these organs may require a low-protein diet. This is to allow the said organ to heal itself first as processing proteins is often an energy-intensive process.

This is especially true in dogs with chronic failure in one or both kidneys. What happens in chronic renal failure is that the kidneys are no longer filtering the blood going through its network of cells. This results in the absence of urine production. The usual high-protein diet of dogs which typically ranges between 30 and 40 percent at the minimum can lead to further deterioration of kidney function. Additionally, since the kidneys can no longer remove the nitrogenous wastes in the blood these byproducts can accumulate and lead to even more serious problems such as encephalopathy and coma.

If you need help finding high-quality dog food for kidney disease, take a look at our buying guide for support and recommendations.

The same is true for dogs that have liver problems such as hepatitis or cirrhosis. Since protein is no longer metabolized, then the accumulation of proteins in the blood can also lead to more serious problems. Reducing the number of proteins taken by dogs should help relieve the burden on this organ.

Of course, if these organs are sick, then other nutrients or substances will be affected, too.

Do take note that a low protein dog diet is not equivalent to a zero-protein diet. As we have already mentioned, dogs need proteins. But if they are sick, especially involving the kidneys or liver, then they will need lower amounts of protein.

The question many pet parents would like to know is how ‘low’ is low?

According to experts, any dry dog food that has a minimum crude protein content of 18 percent can be considered low-protein dog food. In our list of the best low-protein dog foods, you may have noticed that only 2 products, with the exception of Mattie’s Treats, actually comply with the 18%-minimum requirement. The thing is that there is now a paradigm shift in the management of kidney problems in dogs.

Many vets today focus more on phosphorus levels rather than on the amount of protein in a dog’s diet. This paradigm shift is based on the observation that dogs with mild to moderate kidney impairments fared better when their intake of phosphorus was restricted.

However, if your dog has already been diagnosed with severe kidney problem, sufficiently high levels of protein in the urine (proteinuria), abnormally high levels of blood urea nitrogen (BUN), or even hepatic encephalopathy which is the accumulation of nitrogenous wastes in the brain, then low-protein diet is a must.

What are the Benefits of Low Protein Dog Food?

It should be clear from our discussion in the preceding section that low-protein dog foods can also provide a host of benefits, especially for canines that really have a need for such a diet. Let us summarize these benefits in the following points.

  • It allows for organs involved in the metabolism and elimination of proteins and their byproducts to have a much-needed rest, while also reducing the overall work that these organs have to perform.
  • It helps minimize or alleviate the symptoms associated with the disorders in these organs.
  • It helps prevent the accumulation of nitrogenous wastes and other toxins in the blood which can lead to encephalopathy and other serious health conditions for your dog.
  • It aids in the reduction and elimination of certain types of stones or crystals that may accumulate in the urinary bladder, leading to blockage.

Health Conditions that Might Require a Low Protein Diet

The following health conditions in dogs may require limiting protein intake.

Renal Underachiever

Clinical studies have shown the role of restricting protein intake in slowing down the disease process involved in renal failure. It is important to understand what renal failure is. This is a state of the kidneys whereby they can no longer perform their fundamental function of producing urine by filtering blood and removing wastes for elimination in the urine. Because it can no longer remove metabolic wastes, especially the nitrogenous wastes resulting from protein metabolism, then these nitrogenous wastes lead to an increase in blood urea nitrogen. If you give more protein, then there is a tendency that more nitrogenous wastes will accumulate in the blood leading to more problems.

Renal failure in dogs can be brought about by a variety of conditions such as Lyme disease, systemic lupus erythematosus, diabetes mellitus, chronic gastrointestinal diseases, genetic abnormalities, hypertension, and even skin infections.

Protein-Losing Nephropathy

There is also what experts call protein-losing nephropathy of PLN. While this is not necessarily a renal failure, PLN is considered a disease entity that is associated with a rapidly advancing renal failure. The filtering mechanism of the kidneys becomes severely damaged allowing even large molecules like protein to pass through. It’s like having a big hole in your mesh bag that all of your bag’s contents fall off. The same is true in PLN. The holes in the filtering mechanism of the kidneys have become larger, increasing the loss of proteins in urine, a condition called proteinuria. While the natural reaction is to increase protein intake to help replace the proteins lost in the urine, doing so will only increase the size of the ‘holes’ even more. Reducing the protein intake, on the other hand, will also limit the number of protein molecules lost in the kidneys.

Liver Disease

The liver is a very efficient organ especially when it comes to processing toxins. Unfortunately, the liver is not immune to developing problems. When this happens, it will no longer be able to process the various toxins in the body. One of these noxious substances is nitrogenous waste materials. When nitrogenous wastes are not effectively processed by the liver, they accumulate in the blood and can reach the brain resulting in what experts call hepatic encephalopathy. Reducing protein intake will help reduce the number of nitrogenous wastes that the liver will have to process by utilizing whatever limited resources it has left. This can help reduce if not eliminate the accumulation of nitrogenous wastes in the blood.

Bladder Stones

While accounting only for about 6 percent of all urinary bladder stones found in dogs, urate crystals have been shown to respond very well to low-protein diets especially those that come with natural acidifiers like cranberries. The important thing to understand about the use of low-protein diets in dogs with urate bladder stones is that the diet is usually temporary. Once the urate crystals have been dissolved, your dog can return to its usual high-protein diet.

Tips for Choosing the Best Low Protein Dog Food

Now that we’ve covered almost everything about low-protein diets in dogs, let us now focus on how you choose the best low-protein dog food for your pet. Here are some tips on how you can easily accomplish this.

Always Choose Animal Proteins

Whether it is a high protein or low protein, you should always go for products that have animal proteins as their primary source of proteins. Why? Animal proteins are more easily digested by your pet so there are actually more proteins that will be utilized by your dog’s cells. This can also help reduce the number of proteins that are wasted.

Look at the Minimum Percentage of Crude Protein

We mentioned that good low-protein dog food should have a minimum of 18 percent crude protein. Do take note that this is the dry matter weight of the dog food. So if you are going to get wet dog food, make sure to compute for its protein component on a dry matter weight basis. Here’s how. Suppose you have a product that contains 75% moisture and 10% protein. You will have to subtract 75% from 100% to get 25% which is the percentage of dry matter. From this 25%, you will then have to compute the percentage of protein. So, divide 10% by 25% to get 40%. This means the wet dog food actually has a minimum protein content of 40% and not 10% as printed on the label.

Go for Balance

While it is important to reduce protein intake for your dog, you still have to make sure that your dog will be getting a well-balanced meal. This essentially means that dog food should still contain all the fundamental ingredients of well-balanced canine nutrition. You may reduce its protein but if you also increase its fat, then it is also not good.

Feeding the dog

Protein is one of the 3 very important macronutrients that all organisms need to survive, especially our dogs. However, problems in the kidneys, bladder, and liver may require some degree of reduction in our dog’s protein intake. Before you consider any of our 8 best low protein dog foods, make sure to talk with your veterinarian about it first.

    My Scottish terrier has high liver enzymes and needs to be on a low protein kibble. He has been eating Hills Metabolic weight management Lamb&Rice. He loves it and has done well with it. Now they are out of stock and have no idea when they will get it back. They said I’ll probably have to change dog foods. I don’t want to,but have no choice. What can I feed him that will work with his medical issues??
