Dogs vomiting and frothing
Dogs vomiting and frothing may mean that the dog is sick. If the dog is infected with infectious diseases such as parvovirus or canine distemper, it will vomit with foam. If you find that your dog is foaming at the mouth, it is best to deprive the dog of food and water and observe the dog’s condition. If it doesn’t get better, you can test the dog yourself with test strips, or you can take the dog to the hospital for examination.
