Why is my dog drooling, struggling to drink, and mouth won't shut?

Updated on September 23rd, 2025

Pet's info: Dog | Rottweiler | Male | neutered | 3 years old | 106 lbs

My 3 year old male Rott has been having trouble with his mouth/tongue since Saturday. Lots of drool, no scratches or bad teeth. It is almost like his tongue doesn't know how to work. isn't drinking water right, will still eat, but a bit messier. no change in behavior, just drooling, licking, and won't shut his mouth. Vet didn't see anything, sent us home with antibiotics and steroids, but I am still worried.

Poor Thor! I am concerned that he could have a problem with the nerve that innervates his tongue or he could have something like masticatory myositis which affects the muscles of the jaw. Usually with masticatory myositis, the dog will be painful when the mouth is fully opened. If the antibiotics and steroids do not help than consider taking him to a veterinary neurologist or internal medicine specialists for a work up and treatment. If he is not able to drink than your vet can give him subcutaneous fluids to help keep him hydrated.Hope he feels better soon!
