Although dogs are omnivores and need plenty of protein in their diet to be healthy, there is such a thing as too much protein too. Dogs should not eat protein powder designed for humans. In this article, we’ll discuss how much protein dogs need to stay healthy and why you should avoid serving them protein powder.

Protein Supplements and Your Pet

Your pet’s best chance at having a healthy life is a well-balanced diet of quality  protein, fat ,carbs, vitamins and minerals.  There are specifically formulated diets for dogs at different stages of life and with different medical conditions which will provide the ideal nutrition for your pet.

Protein powders designed for human consumption, such as whey protein powder, contain ingredients that could be harmful or even toxic to your pet. Many dogs are lactose intolerant and the lactose in whey protein can cause digestive upsets in high enough quantities. Unflavored protein powder from peas, whey or collagen is unlikely to cause an adverse reaction in dogs if they eat a small portion, but chocolate formulas or artificial sweeteners such as xylitol, are toxic and can make them very unwell. It’s best to keep the protein powders and all other supplements away from your pet unless your vet recommends them.

How Much Protein Does a Dog Need?

It’s recommended that dogs get the following amounts of protein at different stages of their life. The Association of American Feed Control Officials makes the following recommendations for the percentage of protein that a dog should get in their diet;

  • Growing dogs: 22.5% minimum crude protein
  • Adults: 18% minimum crude protein

If you’re still unsure about the correct amount of protein to give your pet, it’s best to contact your vet for recommendations

In older dogs, protein metabolism can be complicated by the presence of multiple diseases. Healthy older dogs may benefit from more protein in their diet, as their requirements increase, but it’s best to speak with your veterinarian before changing anything.

Calcium: Phosphorous Ratio

Meat is commonly used in diets as a protein source however, meat is generally lower in calcium and higher in phosphorus which binds to calcium. Meat only diets lead to problems with bones, gut and muscles due to a relative lack of calcium. Dogs are omnivores and need both meat and vegetation in their diets.

What Factors Can Affect How Much Protein My Dog Needs?

While there are guidelines as to how much protein dogs need, every dog is an individual with their own needs. Some factors affect how much protein a dog needs, and we’ll discuss a few of them below.

Age of the Dog

The age of your dog plays a role in determining how much protein they need. As you can see from the table above, growing puppies need more protein than an adult dog does. However, it is essential to your dog’s balance protein intake and exercise to avoid weight gain and obesity.

Activity Level of the Dog

If you have a working dog such as a Border Collie that herds sheep or a Husky pulling a sled, they probably use a lot of energy. These dogs need higher amounts of energy than other dogs do, which can be supplied in part through increased protein.

Pregnancy

In the third trimester of pregnancy and during lactation, female dogs will have higher calorie and protein requirements and should be fed diets with calorie and protein requirements designed for growth. In addition, make sure the diet is not a restricted calcium diet such as a large breed puppy food.

Health Conditions the Dog Has

Some health conditions that affect dogs, such as chronic kidney disease, can lead vets to recommend serving food with less protein. Prescription diets are often necessary to provide dogs with the appropriate protein, fat, vitamin, and mineral levels.
