My first dog died from a sorta leg/hip disease that he was born with. It only got worse for him when I was in second grade, and he was laying on the floor, practically dying. He couldn't get up to go to the bathroom so he was like, living in his own shit, piss, and vomit. Needless to say, he was miserable. He was also very old but a very sweet dog and I came home one day to my parents crying and saying they had to put him down. I still have my plush that looks like him...
