My dog has bad breath, drools, and won't play. Is it his teeth?

Updated on September 23rd, 2025

Pet's info: Dog | Beagle | Male | unneutered | 1 year and 3 months old | 20 lbs

My beagles breath has gotten so bad, he’s so little that brushing his teeth, especially in the front can be near impossible. I’m afraid now that something has happened either to a tooth or possibly his gums. He no longer wants to play or play tug and is very guarded of his face even just to be pet. His saliva has thickened and when he drinks an increased amount of particles (food and grass from parks) are left behind in his bowl. He is 1.5 years old and has never drooled once, until a 2weeks ago

Poor Felix! I agree, it definitely sounds like something is wrong inside his mouth. He may have a dental problem such as a broken or infected tooth, or may have a wound, a growth, or even some type of foreign body stuck there. I would strongly recommend taking him to the vet for an exam. He/she can do a thorough oral exam (with sedation, if needed) to determine what's wrong, and get him started on appropriate treatment depending on what is found.
