My dog has horrible breath you can smell a mile away. Part of it is she has kidney failure, which I recognize causes foul breath. But she’s also 10 years old and never really had any dental care before. In the last few months, about the time her bad breath became noticeable, she developed nasty tartar on her teeth. She will probably have to be anesthesized to have her teeth cleaned. I understand at her age and health, there is a risk of death. How much should I expect to pay for this type of teeth cleaning?
