My dog is drooling from one side of mouth. Is it a vet emergency?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 61 lbs

Dogs temperament is fine but drool dripping from left side of mouth. Does not seem in pain and will let you open and close mouth. Do we need to take her to a 24 hour vet?

Poor Lola. Unless she is foaming at the mouth, there is excessive drool from her mouth, vomiting, refusing to eat, or acting abnormal then I would watch her closely. If the drool is continuing tomorrow or becomes excessive, then I would consider taking her to your emergency vet. Drooling can be a sign of toxin ingestion but they usually are drilling excessively and it isn’t just from one side of the mouth. She could be drooling due to nausea, a tooth problem, oral ulcers, tumors in the mouth and much more. Your vet will be able to help determine the cause if she continues. I hope this helps.

    Hi. Drooling can occur from nausea, oral infections, GI diseases, and dental problems. She may have an oral issue and some can be painful. I would recommend getting her in tonight or first thing tomorrow for the Gosport aspect. Good luck.
