Of course, it is better to cook it. Raw meat is at risk of being infected by bacteria and parasites. The same is true for fish. It is very necessary to heat and cook it because some fish contain thiamine. Enzyme, which destroys thiamine (vitamin B1), can be destroyed by heating.

Eggs also need to be heated. Raw egg whites contain antibiotic proteins, which will combine with biotin and reduce the efficacy of biotin.

Meat and eggs are both the most important sources of protein for dogs, and eggs are the best source of protein for dogs.

The optimal temperature for dogs to eat is about 40 degrees. Some cold food can be fed appropriately in summer, but it must be heated in winter.
