It's no secret that dogs drool. But why? Find out what's behind all that salivation.
If you own a dog, then you are probably familiar with their ability to salivate from the mouth. Or, what most of us call it: drool. But why do dogs drool? Dog drool is actually just saliva, and plenty of doggy saliva is a good thing! It’s an enzyme-rich substance that’s vital to the swallowing and digesting of food, and has antibacterial properties that fight infection.
Healthy Drooling: Circumstances & Functions
A dog drooling is healthy and a completely normal behavior. Below are some typical functions and situations in which dogs drool:
- Swallowing and digesting food
- Anticipation of a yummy treat or meal time

When Should I Worry about Excessive Drooling?
Excessive drooling is not necessarily more dog drool than you’re comfortable seeing. It means more salivation than normal for your dog. Since you know your furry friend better than anyone, there is no greater person to spot any potential symptoms of irregular drooling. Excessive drooling is called Ptyalism or Hypersalivation, and can be a symptom of the following issues:
- Anxiety and motion sickness
- Oral injury or foreign object lodged in mouth
- Dental issues – tartar buildup, gingivitis, broken tooth, mouth ulcers
- Heat stroke – overexposure to sun and limited access to water
- Eating poisonous plants – tulips, azaleas, and chrysanthemums
Reminder: if your dog displays any of these symptoms, please seek immediate assistance from your veterinarian.
