What's going on with mucus flowing from dog mouth? Mucus flowing from dog mouth refers to the saliva flowing out of dog mouth. This is a normal physiological phenomenon. The saliva in dog mouth is composed of dog secretions and saliva, which can help moisturize the dog's mouth and protect the dog from bacteria and viruses.

1. Heat dissipation

Because the dog's sweat glands are underdeveloped, when the surrounding environment is too high or the dog has just exercised, the dog will open its mouth and stick out its tongue and breathe quickly, which will cause mucus flowing from the mouth. This is a normal phenomenon. Owners don’t have to worry too much. They can move the dog to a cool and ventilated place to rest, and then give appropriate amount of water. After the dog rests for a while, it will improve significantly.

2. Incorrectly eating irritating items

If the dog accidentally licks the disinfectant on the ground, or accidentally eats some kind of irritating food, such as chili peppers, bitter gourd, peppercorns, etc., it will stimulate the dog to spit mucus. This situation is more serious. If the amount is relatively small, you can try to feed the dog a lot of water to relieve the gastrointestinal irritation of food on the dog. However, if the dog eats more chili peppers, it is recommended to take the dog to the pet hospital for gastric lavage or vomiting treatment as soon as possible.

3. Suffering from oral diseases

If a dog suffers from oral diseases, he or she will usually involuntarily flow into sticky saliva, such as gingivitis, oral ulcers, and tartars, etc., and will also be accompanied by chewing disorders, oral odor, decreased appetite, and even waste. Therefore, once the owner finds that the dog has the above symptoms, he or she should consult a pet doctor for medication in time.
