Many years ago I woke in the morning to find my dog in a bad state. I immediately phoned the vet, unfortunately he died while I was on the phone. They were very good, they offered to come and collect him ( for a charge ) or we could take him along. We took him there, still in his bed. They let us take him in round the back so we didn't have to go through reception and then did what they had to do. I'd speak to your vet and see what services they offered.
