First, let me say that Mary Straus at DogAware.com has collected some great research on this subject (and on many other topics). Her web site is highly recommended for anyone looking for in-depth information about protein and kidney disease.
To answer the question, for a long time it was thought that high protein could be dangerous for dogs and harmful to their kidneys. This idea was apparently based on some old research with rats. It’s only been in the last 20 years or so that researchers, vets, dog food companies, and owners have changed their mind about protein. The thinking now has shifted toward feeding your dog plenty of high quality protein.
That still leaves the issues of a dog’s kidneys. Most dogs can eat normal protein diets without any problem. Even dogs with some degree of kidney disease can eat good, high quality protein. They do not have to lower their protein percentage. It’s only dogs with a greater degree of kidney disease who start benefiting from a lower protein diet. But these dogs do start needing a lower protein dog food.
It used to be thought that senior dogs would benefit from eating a lower protein diet but this has also been disproved. However, many pet food companies still make senior dog food with lower levels of protein and lower fat levels. If you have a senior dog, we encourage you to look for a dog food with high quality protein and at least a moderate percentage for protein. You do not have to feed him an extremely high percentage of protein – especially if you are not having his kidneys checked by a vet annually – but it is important for senior dogs to have good protein that is easy to digest. A senior dog can have less efficient digestion as he gets older, so he needs to be able to get the nutrients in the food easily.
Some pet food companies, unfortunately, combine a weight loss dog food with a senior dog food, as though all senior dogs are overweight. This is false. Many senior dogs have trouble keeping their weight. The last thing you want to do is feed them a weight loss dog food that contains fewer calories. You would be starving your poor old dog to death. Unless your senior dog is specifically fat, look for a senior dog food that has a moderately high protein percentage from good quality ingredients, with higher calories, and easy-to-digest ingredients. Even if your old dog is fat, who cares? He’s an old dog. Let him enjoy his food and cherish every day you have with him. Unless your senior dog is so obese that it is endangering his life, you should probably let him enjoy his food. If he is really obese, you can try to find a food with fewer calories or reduce his portions. Try to get him to take some walks. But remember that he is old. You don’t want to do something that might cause a problem for him. Sometimes with older dogs it’s better to leave well enough alone.
It’s also a good idea to keep the protein percentage you feed your puppy in the mid-range instead of seeing how much protein you can give him. The quality of the protein should always be very good, however. With puppies you are not trying to feed them any excess. You want to give them the right amount.
|Species and Growth Stage||Recommended Protein||Recommended Fat|
|Racing Dog||28-34%||Greater than 50%|
|Lactating Dog||25-35%||Greater or equal to 30%|

So, when it comes to lower protein diets, dogs with serious kidney disease or chronic renal failure may need these foods. There could be a few other conditions where a dog might benefit from eating a lower protein diet. But most dogs will do better on a moderate to moderately-high protein diet.
6 Best Low Protein Dog Food Recipes
As you can guess, low protein dog foods aren’t nearly as popular as high protein foods but if your dog needs a low protein diet, then you need to know which foods will meet his needs. Many of the best low protein dog foods are veterinary or prescription formulas so you will need to talk to your veterinarian about buying these foods. You can buy them online from sites like Chewy.com but your vet will need to give you a prescription first.
Other good quality low protein dog foods don’t require a prescription but if your dog has a health issue, you should examine the nutritional analysis for the food carefully to make sure it doesn’t contain too much or too little of any minerals or other ingredients that might affect your dog’s health. The guaranteed analysis will give you a general overview but for precise information you should contact the dog food company and request more precise percentages.
As for veterinary formulas, you may already be aware that many of these foods don’t contain the kind of holistic ingredients dog owners usually like to see in a dog food. There are a limited number of low protein dog foods available today so if you need a low protein food for your dog, you don’t always have a lot of choice. Many people report good results from feeding these foods, even when they don’t especially like the ingredients.
Royal Canin is one of the leaders in prescription diets for dogs. Their renal support diets, such as Royal Canin Veterinary Diet Renal Support S Dry Dog Food, are designed to help dogs with kidney disease. This food was previously labeled as Veterinary Diet Renal LP Modified Dry Dog Food. This is a new and improved formula to make the food more appetizing. However, many dog owners still probably won’t like some of the ingredients. According to Royal Canin, this food has a better aroma and texture to make it more palatable to dogs – something that’s important to any dog who may be experiencing health problems. It should help stimulate your dog’s appetite. This renal support diet comes in nine different feeding combinations (wet and dry). Royal Canin Renal Support Diets A, S, and F have varying protein levels but they are all considered to be low protein. Along with being low in protein, these foods are also low in phosphorus. B vitamins, EPA, and DHA are enhanced; and sodium has been restricted. These foods should slow the development of kidney problems and minimize uncomfortable symptoms.

Hill’s is well-known for their prescription diets. They have a prescription diet for just about every pet health problem you can name. While pet lovers often complain about their ingredients and the cost of Hill’s Prescription Diets, plenty of owners agree that they seem to help pets. Their Prescription Diet k/d Kidney Care with Chicken Dry Dog Food was formulated to support your dog’s kidney function and help sustain muscle mass. Dogs with kidney disease often experience loss of appetite, eating fewer calories and losing muscle mass. This special diet is designed to protect kidney and heart function and support your dog’s ability to build lean muscle. Hill’s formula is supposed to help increase your dog’s appetite and food intake. This food is also made with controlled phosphorus and low sodium, plus therapeutic levels of l-carnitine and omega-3 fatty acids.

While none of the Natural Balance LID Limited Ingredient Diets are specifically designed as low protein foods, most of them have much lower protein compared to other premium dog foods today. They are, as the name suggests, limited ingredient diets. They are formulated for dogs with sensitive digestion. For this reason they tend to be light on meat proteins. These foods can be considered alternative diets for dogs who can’t eat dog foods with ordinary meat proteins and other ingredients. Most of the Natural Balance LID foods are grain free.
