The reasons why dogs keep spitting:

1. Foreign objects such as bones and food are stuck in the dog’s teeth, which makes the dog feel uncomfortable in the mouth and secrete more secretions. Saliva leads to spitting.

2. Dogs accidentally eat hot peppers, disinfectant water and other irritating items, which stimulate the secretion of saliva in the mouth and cause spitting.

3. Dogs suffering from oral diseases, such as periodontitis, oral ulcers, etc., can also cause spitting.

Solutions for dogs that keep spitting:

1. If it is caused by a blockage caused by a foreign object, it is recommended that the owner open the dog's mouth with his hands and gently remove the foreign object. Clean it up.

2. If it is caused by accidentally eating an irritant, it is recommended to rinse the mouth with saline and provide enough drinking water.

3. If it is caused by oral disease, it is recommended to consult a doctor for medication.
