Is 30 protein too high in dog food
Can Dog Food Have Too Much Protein?
Of all the nutrients in dog food, protein is the one that gets the most attention. We know its crucial to dogs development and lives. But can you have too much of a good thing?
The Dog Food Advisors nutritionist, Laura Ward, discusses the highs and lows of protein in dog foods and how much is too much.
__________________________
If youve checked out the AAFCO Nutrient Profile, youll know that the minimum protein requirement for adult dogs is 18% and for puppies its 22.5%. This is expressed on a dry matter basis or DM, a way to compare foods of different moisture (such as a wet food and a dry food) by theoretically removing the water content.
However, theres currently no nutritional maximum for protein so what does that mean for our dogs food? How much protein is too much?
How high is high-protein?
We consider any diet with a DM crude protein content of more than 28% is high-protein. It isnt unusual, however, to see protein levels above 35%, or even over 40% in dry foods. In fresh and wet foods this is often greater, at around 60% DM. This high protein bracket, therefore, covers a wide range of protein possibilities.
Benefits of high protein in dog food and when to be cautious
Protein is linked to palatability for dogs, so high-protein foods are usually super tasty. Dogs will often choose a high-protein food over a lower-protein option, so if you have a fussy eater, high-protein food can be a great choice. There are other scenarios too where higher protein is particularly valued.
For active or working dogs, the protein they need for maintenance is increased. Not only is there a greater need for the replenishment of muscle tissues, but other changes in the body require proteins from the diet too. This is because endurance activities require more efficient delivery of oxygen and nutrients to muscles, which the body becomes conditioned for, just like with human athletes.
These changes include increased blood volume, red blood cell quantity, and increases to other parts of the body cells used for energy generation. The protein building blocks for this come from increased protein being delivered through the diet.
Its also important for senior dogs to have a high-quality source of protein in their diet. Protein, making up a larger proportion of the calories in a senior diet, can support their lean muscle and help to avoid the muscle-loss associated with ageing. Moderate- to high-protein wet or fresh food options can be good choices for senior dogs, as they improve hydration, are very palatable, and are also soft on weaker teeth.
Weight-loss is another situation where protein is important. The energy (or calorie) content of the food is carefully controlled to aid weight loss, but its also important to support muscle. A good quality protein supply and higher-protein content in the diet is essential to avoid muscle wastage.
However, dogs are more likely to eat more of a high-protein diet, which is counterproductive for weight loss. High-protein diets at the higher end of our high protein range (more than 35% DM) are often particularly nutrient dense and can be ill-suited for weight loss. Dogs need only a small quantity of these foods which, when combined with weight loss measures, can leave dogs fed a high-protein diet which isnt designed for weight loss, feeling hungry.
For pregnant and nursing dogs, protein is a crucial element of the diet. During these phases, the requirement for proteins, through changes to the body and the development of puppies or the supply of milk, is great. AAFCOs nutritional profile for growth is most suitable for pregnant and nursing dogs, to represent this increased requirement. High-protein foods can be a great choice during this time.
With diabetic dogs, its the carbohydrate content of food which is the greatest focus. As diabetic dogs cannot safely regulate their response to blood sugars, carbohydrates should be limited in the diet. This generally means that energy is primarily supplied by fats and proteins in the diet to minimise peaks and falls in blood sugar after meals. High-protein and low-carbohydrate foods are recommended, but your veterinarian will advise further what this looks like for your dogs diet.
In the case of any susceptibility to kidney problems, or renal insufficiency, take advice from your veterinarian before feeding a high-protein diet. Although its important for dogs with renal insufficiency to still have a high-quality source of protein in their diet, diets which contain a moderate, rather than high, protein content are often more suitable.
Studies have shown that protein is not connected to the progression of chronic renal failure, however, recent studies have also found high protein (46%) can be linked to an increase in markers of kidney dysfunction. Although veterinary advice now doesnt call for protein restriction, it often recommends avoidance of excessive dietary protein.
Whats wrong with low-protein dog foods?
A real low-protein diet is only available when prescribed by a vet, as feeding a low-protein diet without medical need could cause deficiency diseases in a healthy dog. There are foods, however, which meet AAFCO protein requirements without supplying very much extra protein. These foods supply the majority of the energy from fats and carbohydrates.
This is often associated with lower quality or cheaper foods, as protein is often a key driver of cost in a dog food recipe. As protein is linked to palatability in dogs, lower protein foods can be less tasty.
Carbohydrates are broken down differently to proteins, into sugars. The carbohydrate source in the recipe determines how the blood sugar is affected. For foods which are high on the Glycaemic index, a peak, followed by a fall in blood sugar is seen. Although not an area which has been sufficiently studied, this is thought to be linked to fizzy and lethargic behaviour like children fed sugary foods.
Summary how important is protein in dog food?
The quality of the protein in a food is far more important than the quantity. A protein source which supplies all of the amino acid protein building blocks in the correct quantities and in a digestible and accessible form is the goal.
There are certainly benefits to be gained by supplying high levels of protein in a dogs diet, but the effects of some of these super-high-protein foods are not well studied yet. If in doubt, feeding a moderately high protein food to begin with of 28% to 30% DM protein and monitoring your dogs reaction is recommended. Remember, you can always ask your vet about changes to your dogs diet.
Best High Protein Dog Food in 2024: More Meat = Happier Dog
Looking for the best high protein dog food? The term high protein dog food, we always hear it, but do we know all about it? Read on.
At one time most dog foods were fairly similar in terms of their protein percentages. They tended to follow government recommended minimums for dogs.

A few companies had some higher protein formulas (Purina Hi Protein and some other higher protein foods were available in the 1970s) but they still used the same kind of ingredients found in the other foods of the time and relied heavily on grains.
If you wanted your dog to have more meat protein you could add some canned food (average quality or less) or meat from your own refrigerator.
Today, of course, many dog foods have higher percentages of meat protein. The current recommended minimums for protein in dog food are 22 percent for growth and reproduction (puppies); and a mere 18 percent for adult dogs (AAFCO Table 3).
Nearly all commercial dog foods have higher protein percentages than these figures. Many premium dog foods have 30 percent protein (DMB) or more.
At different times in a dogs life he can need different protein levels, depending on his activity level:
Species and Growth Stage | Recommended Protein % | Recommended Fat % |
Puppy | 28% | 17% |
Adult dog | 18% | 9-15% |
Performance dog | 25% | 20% |
Racing sled dog | 35% | 50% |
Lactating dog | 28% | 17% |

The Benefits of High Protein for dogs
For most dogs, yes, more protein really is beneficial. According to one study, wolves have a protein-fat-carbohydrate profile of 54:45:1 percent by energy; while modern dogs have a profile of 30:63:7 percent by energy.
Our modern dogs do not eat a diet like that of their wolf ancestors, but your dog wont thrive if you feed him nothing but meat.
However, a diet thats high in meat protein is fine for most dogs unless they have a particular health problem that contraindicates high protein.
Protein helps build lean muscle; makes the skin and coat healthy; heals wounds; and supports the immune system and central nervous system.
If your dog doesnt have enough protein in his diet, he can start to break down protein in his body to get what he needs which results in muscles wasting.
Without enough protein the immune system suffers and a dog can be more susceptible to injury and stress. Modern dogs have evolved from their wolf ancestors and they are able to digest carbohydrates but dogs can still benefit from eating high protein diets.
At one time people thought that high amounts of protein might lead to bone problems in puppies or cause older dogs to develop kidney disease. These beliefs have been disproven.
Most dogs with kidney disease can benefit from eating a diet with moderate protein. Puppies may develop bone problems from too much calcium but not from too much protein.
High protein for adult dogs
Today many grain free dog foods are particularly high in protein. Some of the protein comes from meat protein but often some of the protein comes from peas and lentils.
Your dog can benefit from plant-sources of protein but dogs do not digest these sources of protein as well as animal-based sources. This was one of the complaints about using grains in dog foods they are also a plant-based source of protein as well as a source of carbohydrates, just like legumes.
Grain free dog foods that dont use legumes typically use starchy carbohydrates such as potatoes, sweet potatoes, tapioca, and other carb sources.
While some of these high protein foods may have lower carbohydrates than foods with grains, they can have their own dietary issues for dogs.
If you look for foods that have more meat protein, they will generally have fewer carbohydrates, no matter the source of the carbs whether it is peas and lentils, potatoes, or grains. However, many high protein dog foods are also high in fat.
While fat is not all bad, especially for very active working dogs, its not good to see too much fat in a diet for most of our couch potato pets. If your dog is overweight or if he has problems digesting fat, look for dog foods that have slightly less fat but are still high in protein.
You dont have to choose a low calorie or weight control dog food. Just check the fat percentages (DMB) and opt for a food that has slightly less fat.
Many people like Wellness CORE because it has slightly less fat while still providing high protein. In general, look for a dog food that has twice the protein percentage as the fat percentage.
High protein for older dogs
Older dogs can benefit from eating more protein, especially protein from good quality sources that are easy to digest. Many dog foods for older dogs are formulated with lower protein, along with lower fat and calories on the assumption that most older dogs are overweight.
Yet many older dogs have trouble metabolizing nutrients as they age. Instead of reducing their protein percentages, they will do better with more protein to help keep their immune system strong and to prevent their muscles from wasting.
Be careful in selecting dog food for your older dog, especially if he is not overweight. Dont choose a food with lower calories unless he needs that kind of food. Look for a food with plenty of good protein regardless of whether the food has fewer calories or not.
High protein for puppies
You can also feed puppies high protein diets as long as long as you are feeding a good puppy food or all life stage food. You do need to pay close attention to the calcium percentages when dealing with high protein foods and puppies.
The calcium percentage needs to be 2 percent or less (DMB) for large breed puppies under six months of age. Large breed puppies, in particular, can grow very fast. They can be susceptible to skeletal and joint problems if they have too much calcium at a young age.
Adding protein to your dogs diet
If you are feeding a good dog food but the protein percentage is on the low side, you can increase the protein in your dogs diet by adding eggs, meat, fish, or other sources of animal protein.
There are also some good supplemental dog foods that are 95 percent meat. These foods are not sold as complete and balanced meals for dogs but they make excellent toppings for your dogs dinner and add good protein to his diet.
Quality protein
Its important to remember that its not just the percentage of protein in your dogs diet that matters. Your dog could eat a food with 40 percent protein but if the food is made up of low quality protein, your dog will not be able to digest it as well or obtain the nutrients from it.
As already mentioned, many grain free dog foods today include large amounts of peas and lentils which are high in plant protein and not as easily digested as animal protein.
In 2007 melamine was added to wheat gluten from China that was then (unknowingly) used in some pet foods. Melamine is an organic chemical that is normally used to make plastics. However, it is also a high nitrogen compound.
This means that if it is illegally added to glutens or other food items, it makes those foods appear to have a higher protein content. (Ingredients are often tested for protein based on their nitrogen content.) This is just an example to show that not all proteins are the same.
When choosing a high protein dog food, dont just look at the percentages. Check the ingredients carefully.
Risks of high protein diets
Some foods today probably do have more protein than dogs need. It is possible for dogs to become overweight by eating too much protein. Calories are calories, even if they come from protein.
While some excess protein can be excreted in your dogs urine, protein can also be stored as fat if your dog is using all the protein he needs in his diet.
Protein metabolism also uses extra water in the body so a high protein diet can lead to dehydration unless you make sure your dog gets plenty of water. You may have noticed that many dogs drink more water when they are switched to a higher protein diet.
Eating higher amounts of protein can also cause the body to expel more calcium which can weaken bones over time so its always important to keep an eye on the calcium levels in high protein dog foods.
You probably wont need to worry about most of these issues unless you are feeding your dog a very high protein diet.
Summary
High protein is good for most dogs unless they have a specific health condition that indicates they should avoid eating too much protein. Many of the myths about dogs eating too much protein that people believed at one time (dogs and kidney problems, puppies and protein, old dogs) have been disproven.
In general, the more meat protein a dog food contains, the fewer carbohydrates the food will have which is better for your dog.
