It looked like maybe a pitbull and a boxer, but I couldn't completely tell. I was driving past and have been feeling bad that I didn't pull over to help. The owners were clearly in over their heads with the owner of the dog getting it's throat ripped out freaking out and the other standing back like there was nothing she could do about it.
In the moment I wasn't ready to put myself in harm's way for a dog that was probably already beyond help. I'm not an animal person and really dislike dogs. If I could get a do-over I would do better though.
