Why Is My Dog Drooling Excessively

This page is educational reference material for preparing questions. A licensed veterinarian examines the animal, makes the diagnosis, and sets the treatment.

Excessive drooling in dogs beyond normal: nausea, dental disease, poisoning, heatstroke, and oral tumors.

Understanding This Symptom

The dog who seems "a bit off" today is giving you the earliest possible warning — and the version of you that notices early is the version that saves money and suffering later. This guide focuses on the most common causes, warning signs that indicate an emergency, and what you can expect at the veterinarian.

Should I go to the emergency vet?

Go now if the drooling comes with a swollen face, trouble breathing, tremors, or a known chemical or plant exposure. A stick in the mouth that the dog is pawing at should be seen the same day. Mild drool that stops when a meal is finished can be mentioned at the next visit.

How much will treatment cost?

Sudden drool means the mouth is examined for a stick, a bad tooth, or a burned tongue, and the rest of the exam looks for nausea. Sedation to remove an object is priced separately from the look in the mouth. Ask before that step.

Can I treat this at home?

Check the gums and the tongue with a light if the dog will let you, and note any plant, chemical, or bone the dog had. Foaming plus trembling or a swollen face should be seen now. Wipe the slime away so you can see the color of the gums.
