What happens if a puppy eats egg white?

A puppy that eats too much egg white, which is high in protein, may suffer stomach upset with diarrhea, vomiting, and abdominal pain. Also, although egg white is rich in protein, it lacks other nutrients like fat, vitamins, and minerals; long-term feeding can cause nutritional imbalance. Finally, excess protein increases the burden on the puppy’s kidneys, and eating egg white regularly may damage the kidneys or even lead to kidney disease.
