I know how you feel! I remember whe Lucy went for hers. Speak to the vet, we did and ours was very sympathetic and we were allowed to stay with Lucy from when she had her sedation until she was really dopey. Does Coco get panicy at the vet? Lucy does and again the vet was sympathetic and made sure that her op was done first so that she did not have the stress of being stuck in a kennel without Mum. They know how hard it is for you and any vet worth their money will try to make it as easy on the both of you as possible
