My 12 year old dog has a lot of tartar on her teeth and the vet has recommended a clean under a general anaesthetic. Apart from the cost (£500), I am concerned about her surviving the procedure. She has heart issues and is on 3 types of tablet. But would it be better to have it done now rather than later when she is older and it becomes a necessity due to teeth needing to be removed or something? I just can't seem to make a decision - if she passes away under the general anaesthetic, I'll blame myself. Has anyone been in this position before?
