Excessive drooling can cause dehydration in your dog - which can then cause further problems. Saliva is necessary to provide enzymes to help swallow and digest food, but too much of it could be the sign of a problem with your pet.

- Trauma: Your dog could have suffered an injury to the mouth or throat area. Check the inside of your its mouth for any foreign objects, such as splinters, and for any signs of a cut or gash. If there is an object in there, then it would be best to get your vet to remove it.
- Infection: Sometimes excessive drooling can also be caused by infection, which can be bacterial, fungal or parasitic. A vet will be able to start your pet on a course of antibiotics in order to treat the problem.
- Growths: Cysts or other forms of growths inside your dog's mouth may also cause these symptoms. Again, it would be best for the vet to take at look at this problem.
