Technically called ptyalism or hypersalivation, excessive drooling is somewhat common in dogs but can occur among cats and other pets as well. Drooling is just the extreme of a natural response to food stimuli or a dry mouth. However, it can be a messy and unappealing trait in your pet, and pet owners don't have to deal with their dog drool without relief.
Caution: If excessive drooling is a new trait in your dog, pay attention to additional signs of distress, pain around the mouth or head, or other symptoms of a more serious condition.
Natural Cures: Slipping a bandanna around your dog's neck can help reduce and collect excess drool. Meals and excitement can increase drooling, so plan for these occasions.
