Q. He has lost hair an now scabby sores have formed in the area, he has also recently started vomiting ? What do I do
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. The changes to the skin could be the result of parasites, like fleas or mites, or he could have allergies to the environment or to an ingredient in his food. The vomiting could be a sign of many different problems - a foreign object in the GI tract, an infection, kidney or liver disease - or it could be another sign of an allergy to food. He needs to be examined by a vet who can help you start working through these problems and figure out the best way to treat them.
