What happens if a dog is fed milk powder?

Feeding a dog milk powder can cause indigestion and nutritional imbalance, because a dog’s gut has little lactase and cannot digest milk lactose like humans, so milk powder may lead to diarrhea, vomiting, and abdominal pain. Second, milk powder’s nutrition is not well suited to dogs and can cause imbalance and extra kidney strain; its high calcium content, if over-consumed, may also cause bone problems. Finally, some dogs may be allergic to ingredients in milk powder, showing itchy skin, redness, vomiting, and diarrhea.
