What Harm Do Worms Do?
Once swallowed, eggs and larvae develop into adult worms inside the dog, and although they spend the greater part of their lifecycle in the gut, part of their time may be spent in the liver or lungs. During this time they cause inflammation of the liver, lungs, stomach and intestine. Depending on the type of worm and the degree of infestation, worms may cause abdominal pain, indigestion, bloody droppings, weight loss, poor coat condition, and blood loss associated with anaemia and diarrhoea. Because diarrhoea involves abnormal fluid loss and decreased food absorption, an infected dog (especially a puppy) is in danger of dehydration, and in severe cases, death.
