Wow that is frightening..
I am having a similar problem!!! Mari, my 2 yr old 4 #, has taken to attacking Rico, my 13# Chihuahua, at night in bed if he gets near her or me. I mean she growels, then 'flys through the air' and attacks. I am so afraid he will bite her before I can get her away from him. This started about a month ago. My husband says put her in a kennel, but I know she won't go for that.
Does anyone have advice?
