What happens if a puppy drinks too much goat milk?

Drinking too much goat milk can cause indigestion and vomiting in a puppy, because its digestive system is still immature and its stomach capacity is small. Too much milk at once overloads the stomach and cannot be absorbed quickly, causing bloating and vomiting.

Also, a puppy should start eating kibble at about 45 days old and eat dry food at 3 months. If it only drinks goat milk it will soon feel hungry and need frequent feeding, which is also bad for its dental health.
