Usually, the causes of the above symptoms in dogs include infectious diseases such as parvovirus, acute gastroenteritis, intestinal obstruction, etc. At this time, the dog should be given no food or water, and then use infectious disease test strips for testing. If it is canine distemper, parvovirus, or coronary problems, go to the hospital for treatment in time.

Poisoned dogs may also show symptoms of vomiting without eating or drinking, and lack of energy. At this time, you must first drink soapy water to induce vomiting, and then send to the hospital for emergency treatment. During the treatment period, the owner can feed the dog some easily digestible food that the dog likes to eat to increase the dog's appetite.
