dog died

My parents dog was put down this morning.
(more after the cut)

I've known her since I was 15. I've never had a dog die. It's pretty damn sad. My dad is really torn up about it. He really put a lot of effort into keeping her but she just got too crazy. She was fine physically, but she was quickly going crazy. She had very severe separation anxiety disorder, every time my father would leave the house she'd go crazy, try desperately to get out, and now was becoming a danger to herself and others. She had gotten out and tired to bite our neighbor. My sisters don't know yet, so I'm sure it'll be a sad evening at my folks house tonight.

I'm sad.
