We don't know the full story. I can understand someone not wanting to risk their pet ending up in a shelter, being pts by strangers after days/weeks/? in a very stressful environment. We don't know if the dog had health or temperament issues. Thinking about possibilities like this and having a plan is important when you have pets, who do you know you could turn your animals over to right now, that would take equal quality care for them forever? My dogs would have no place to go but the shelter and for two senior pit bulls used to the couch life, I would choose quick death. Ultimately this dog had a home with an owner who cared for it for and and a peaceful end and that is not a bad life at all.
