8. Raw meat
Eating raw meat may seem natural, since this is what dogs in the wild consume. Domesticated dogs, however, do not have the stomach to consume raw meat that may be filled with harmful bacteria. The increased bacterial proliferation on the meat and other possible contaminants can have a negative affect your dog's digestive system -- and bones from raw meat such as chicken pose additional hazards.
9. Raw eggs
Eggs may be high in protein, but they are also ideal for bacterial growth. Raw eggs may also decrease the absorption of biotin, leading to skin and coat problems that make your pet uncomfortable. Eggs can be fed to your pet, but must be boiled or fried to prevent problematic side effects.
10. Milk and Dairy
Some dogs enjoy drinking milk, but unfortunately, they are not capable of digesting the lactose in milk and other dairy products. This causes soft stools and watery diarrhea, which is not just a mess but could cause dehydration. To avoid this problem, use lactose-free dairy products for your Shih Tzu.
