A Little previous info..
I got my dog Taura (avatar pic) about a year and a half ago. Shes been a good dog always with me on hikes and throughout the day just hanging out, but she also had her problems. She has issues with other dogs so I always kind of kept her away, and everything was kind of ok. She had seperation issues also and with school coming up i've been leaving her with my grandparents to get used of them, and being away from me. Well today was my second day of school and I left her with them. I come home, grab a snack and all of a sudden theres panic in the back yard. I run out there to see one of his granparents chihuhua (who lives in the back) flailing around with blood everywhere. It was such a hard sight that I still can't get out of my head. Taura had bit the dog in the neck over some food I'm guessing. I couldn't believe it, but then I could. I'm so upset that she did this and have decided not to keep her anymore. This rainbow bridge post is for that poor little dog that had to suffer becasue of taura.

If you were in my position would you take the dog to get put down? or simply try to get her into a rescue? would you tell the rescue what she did? Please I need some guidance.
