Q. My cocker spaniel horrible bad breath. & it looks like her entire gum line/inner lips look like it's all a big canker sore. What is it & what do I do
A. Gum disease and tartar are quite common in Cockers. If he´s build up tartar the best treatment is Scale and Polish at your vet under general anesthetics, and normally we recommend antibiotics previously to reduce the infection around te teeth and do the dentals safely. The bad breath is produced by the bacterias eating from the food remaining on the teeth/gums. A good teeth brush will help as well and can prevent the tartar after your vet remove it.
