After the owner discovers that the dog has drunk tea by mistake, he can let the dog drink more water. Some dogs will have gastrointestinal discomfort after drinking tea, and they will actively look for food or plants to relieve it. In fact, if the dog just drinks tea, there is no serious problem. If the dog eats tea, it will be very serious. The dog will vomit, foam at the mouth, and have convulsions all over the body after eating tea. The owner should send him to the doctor in time.
