Why is my dog drooling so much all of a sudden? Is it serious?

Updated On September 23rd, 2025

Pet's info: Dog | Pug | Female | spayed | 21 lbs

My dog is drooling, A LOT. So much that it has kept her up pretty much all night. She is leaving huge wet spots wherever she lays her head. It is unusual for her to drool like this.

Drooling can be caused by a lot of things, and Penny will need to be examined by a vet to determine what could be going on. Nausea is the most common cause, followed by oral pain. Dogs with hypersalivation should have a thorough medical history discussion and physical exam. Physical exam will evaluate all of the oral structures, and the vet may need to sedate for a more thorough oral exam.

    This sign is usually related to nausea, but dental problems, and some type of intoxications are possible as well. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately.

    This can be due to nausea, toxicity or stress. If he is behaving normally otherwise, you can clean him up and monitor him at home. If he is lethargic, develops tremors or difficulty breathing or starts vomiting or has diarrhea then he should be seen by your veterinarian or at the nearest veterinary ER.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Lily! Possible causes for drooling are: nausea, toxin ingestion, licked something that tasted bad or was irritating, infected teeth, tumor or ulcer in her mouth, foreign material (stick) stuck in the mouth, seizures, metabolic conditions like liver or kidney disease or issues with the salivary glands. If the drooling doesn't resolve, she is having trouble swallowing or won't eat then she should be seen by a Veterinarian. I hope this helps and I wish Lily the best!
