Worms are common in Dogs and can be easily treated. Worms are cause of various problems in dogs such as Diarrhoea, dehydration and anaemia. The dog might lose weight, cough, have a rough dry coat and a pot bellied appearence. In serious cases, worms might block the intestines causing death of the dog. Puking can be a symptom of worms in your dog so you better get it treated by a vet.
