Raw fish and meat can contain bacteria, such as E. coli, that cause food poisoning. In addition, certain kinds of fish like salmon, trout, shad or sturgeon can contain a parasite that causes "fish disease." If it is not treated, the disease can be fatal within 2 weeks. The first signs of illness are vomiting, fever and large lymph nodes. Thoroughly cooking fish and meat will kill the parasite and protect your dog.
Raw bones may seem like a great idea for dogs, but for domesticated pets it can be very dangerous. A domesticated dog might choke on the bones if it splinters and then becomes lodged inside your pet's throat.
