My dog has bad breath, drooling, snorting, and a dry nose. Why?
Hello. I’m sorry for your frustration, but some further investigation by a veterinarian is needed in order to determine what is going on. A thorough oral exam to look not only at the teeth but under the tongue, and all over the inside of the mouth for evidence of any growths, foreign bodies, etc would be the first step. This often requires sedation and dental X-ray may be helpful. Leo could also have something in his sinus or nasal cavity.....something stuck in there, a growth or polyp or just a deep seated chronic infection. Sedation to examine above his soft palate and then to flush his nasal passages would be recommended. If these things are not done to try to find the underlying problem, all you can do is continue to try antibiotics. If penicillin has been tried twice, it’s time to move on to a more broad spectrum one. However, I would be concerned that there is something more going on and the additional investigation would be best.
