I clean my dog's teeth at the front, but clearly haven't been doing a good enough job at the back, as I've just noticed he has plaque and a bleeding gum right at the back. He is a lovely fellow and quite amenable to my delving around at the back of his mouth.
What should I do? I've just been scaring myself witless by googling and seeing that this could lead to bacteria travelling round the body etc. Is this a vet issue or something I can deal with?
