Soy protein has been successfully used as a plant-based protein source for many years and is primarily used as a base for meat and dairy substitutes. Soy also plays an important role in vegan dog nutrition, ensuring that dogs receive a balanced and nutritionally appropriate diet.

Can dogs eat soy?

In short: Yes, dogs can eat soy.
Cooked soybeans are well-tolerated by most dogs and are already a regular ingredient in many dog ​​foods. It is important that the soy is processed. Raw or dried soybeans are not suitable for dogs.

What is meant by soy and soy protein?

The soybean belongs to the legume family and is a first-class protein source that offers your dog an optimal amino acid composition.

Soy is also rich in important vitamins, minerals, and trace elements, as well as unsaturated fatty acids, which are essential for maintaining muscle mass, strength, and energy. It also contains valuable antioxidants that significantly contribute to strengthening the immune system.

At Vutter!, we use non-GMO soy that is carefully processed to preserve its nutrients and health benefits. Since its protein content is nearly identical, soy is an excellent alternative to animal protein and is in no way inferior to food made from conventional meat.

At Vutter!, we don't use the whole soybean, but only isolated protein. The bean is processed in such a way that we don't use the entire bean for the final product. This allows the protein to be absorbed more effectively, among other benefits.

The advantages of soy protein at a glance:

  • Protein content comparable to that of meat
  • Better absorption through isolated protein instead of whole beans
  • Excellent alternative for dogs with intolerances or allergies

A purely plant-based diet for dogs is possible if the dog food is formulated to meet their nutritional needs. Vutter! wet food is a complete food based on soy and therefore provides your four-legged friend with everything they need for a healthy and happy life. Studies also show that dogs do not experience any adverse health effects from a balanced vegan diet.

It is generally possible to feed a puppy a purely plant-based diet. However, this requires that you feed your puppy only food specifically formulated for puppies. Any change in diet should always be professionally supervised to ensure your young dog has the best chance of growing up big and strong. Our experts have developed Vutter!'s vegan complete food specifically for the needs of adult dogs. Therefore, Vutter! is not suitable for feeding puppies. Once your dog is fully grown, there's no reason not to switch completely to our wet and dry food.

Soy for dogs with allergies

Soy is not a typical allergen. In fact, dogs react much more frequently to animal proteins than to plant-based ones. A plant-based dog food containing soy is particularly suitable if your dog suffers from an allergy to animal proteins.

Most dogs generally tolerate soy without problems, however, individual abnormalities should be observed: Pay particular attention to symptoms such as vomiting, diarrhea, flatulence or skin reactions and seek veterinary advice if you are unsure.

All the important information at a glance

Soy is an excellent way to meet your dog's protein needs and is a great alternative to animal proteins if you want to feed your dog a plant-based diet. It provides essential amino acids, important vitamins and minerals, and is particularly suitable for dogs with meat intolerances or as part of a vegetarian or vegan diet.
