Vomiting and drooling in dogs may be caused by improper diet, food poisoning, parasites, viral infections, etc. The dog’s mental state needs to be observed. If the situation is serious, it needs to be sent to the hospital for treatment in time. Special attention should be paid to the diet. Do not feed the dog hard, irritating, or difficult-to-digest food. Deworm the dog on time and feed it some probiotics in an appropriate amount, which can help the dog regulate its stomach.
