Apologies for posting in AIBU, and for the fact that this subject matter will be upsetting to some people.
I need to accompany someone else's dog to the vet's to be put to sleep later today, and, as I'm very, very fond of this little creature although he's not mine, and am very sad, could someone please explain to me exactly what happens in as much detail as possible when an animal is euthanised?
I'm not a pet owner, and have never been to a vet's, far less for this procedure, but though I'm very apprehensive, it's absolutely the right decision, and I want to be there for him to the end. (Am I even allowed to stay?) I'd just like to know in advance what will happen so I can be more attuned to this little dog.
Thank you so much.
