I know EXACTLY how you feel Dee. I too went through the same thing with my precious dog a couple of years ago. He was 10 at the time. I thought what if he dies under anaesthetic just to have his teeth cleaned, how would I forgive myself. BUT they needed doing and I didn't want him to have bad teeth (I got him as an older dog and he'd been neglected, hence his dental problems). I went through the mill while he was at the vets, but of course he came through it and woke up with a healthier mouth. I think we all worry about an anaesthetic as our pets get older, but the vets do take our concerns into consideration. Good luck.
