How do I stop my mastiff from drooling?
Oral Hygiene Issues
The best way to prevent this problem and the associated drooling is to brush your dog's teeth on a regular basis, make sure he has plenty of dental chews, and has a regular checkup with his vet.
Do mastiffs always drool?
Mastiff. The amount of drool a Mastiff produces is on par with his giant size. Most Mastiff owners learn to distribute hand towels throughout the house to wipe the dog's mouth, especially after he has lapped up a large amount of water. Take a cue from experienced Mastiff owners and always be ready with a wipe!
