Has anyone ever had to be in the vets office when their dog is put down? I hope they are very understanding of a grown man breaking down like a little girl, because I'm fairly sure that's what I will do when the time comes. Hopefully my dogs die peacefully in their sleep.
As a Vet Tech I saw this almost weekly. I'd really recommend any person staying behind.
If you have brought your pet to the vet regularly it's really not a stressful thing for them...it's usually the ones with 2" long toenails and matted fur that freak out.
Also a vet coming to one's house may not always be the least stressful thing for the pet. They sometimes can sense something is 'different'.
You have to know your own pet.
I haven't seen many not cry when their pet goes.
One of the things many don't think about is what to do with the deceased pet. Cremation is reasonable...some places do not allow burial on residential property. A vet will sometimes do a necropsy (autopsy of an animal) if they were in treatment to verify things. The animal is then wrapped up in a plastic bag and frozen until a collector comes for the bodies. The vet will know where those bodies end up.
It's morbid, but better to plan ahead than call a week later hoping to get your pet back.
