1. Dogs with canine distemper
Dogs with canine distemper are likely to refuse to eat, become lethargic, and in later stages may even foam at the mouth and convulse all over the body. At this time, the owner needs to cut off food and water to the dog, so that the dog will not be deficient because of excessive vomiting and diarrhea.
2. Gastrointestinal discomfort
If the dog is foaming at the mouth and not eating, it is likely to be caused by eating leftovers, poor-quality dog food and other difficult to digest and absorb food. Some puppies even refuse to eat because of a cold or flu.
3. Stress reaction
Some puppies that have just changed to a new environment are likely to have a stress reaction due to excessive shock and panic, not eating and no spirit. At this time if the owner to feed the dog deworming drugs and other drugs, may also lead to foaming at the mouth, which is normal.
4. Food poisoning
Some dogs, when food poisoning, will also foam at the mouth, do not eat, no energy. This time the owner can first give the dog with some saline gastric lavage to dilute the drug, and then take the dog to the regular pet hospital gastric lavage treatment, if necessary, injection of diuretics to urge the dog to urinate.
