...my puppy was as old as I was when I had to put him to sleep...he had a growth that appeared on his stomach that eventually became an abcess...he stopped eating, then he stopped drinking, and eventually stopped walking. so one morning, I walked down to his house, wrapped him in a blanket, picked up him, and walked him to the vet that's a few houses up so he could be put to sleep. he was eight-teen and I was eight-teen...I miss my puppy.
