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?

Excessive drooling is called Ptyalism or Hypersalivation, and can be a symptom of the following issues:

Reminder: if your dog displays any of these symptoms, please seek immediate assistance from your veterinarian.
