9. Raw eggs
Eggs may be high in protein but are also ideal for bacterial growth. Raw eggs may also reduce the absorption of biotin, leading to skin and coat issues that make your pet miserable. Eggs can be fed to your dogs, but they must be boiled or fried to prevent troublesome side effects.
10. Milk and Dairy
Almost all dogs enjoy drinking milk, but sadly they are unable to digest lactose in milk and other dairy products. This causes soft stools and watery diarrhea, which is not just a mess, but may cause dehydration. Use lactose- dairy products for your Shih Tzu to avoid this problem.
