We HAVE to put my doggie down. Its happening now!

My poor Truffle, she looks terrible. She is 15 and on deaths door. She hasn't kept food down in a week and she looks like she is in pain when she stands. She has dropped from her life long weight of 4 1/2 lbs, to only 3 lbs. She keeps looking at my mom and I with a look like she is asking us to die. My mom was holding off until my dad got home from Ohio, but my guess is it will be tomorrow or Monday at the latest.

I got her as a present for my 8th grade graduation, although really she is more my mom's dog, and Cookie, who was my grandmothers has become mine. But she is still my doggie and I am so sad.
