Last night I was walking my 3 dogs, on leash, as I always do and a daschaund he wanders the neighborhood off leash just walked right up to the 3 dogs. The 2 bigger ones, both mixed breeds, but appx 50lbs, absolutely tore into this poor little daushand. One had one side of her, and the other had her neck.........and they would not let go. It was like watching a Nature special of lions eating their prey. I screamed so loud for them to stop and tried to pull them away and off of the dog -but I did not want to let them off the leash because I was afraid they would take off with the dog, so it hindered me trying to get them all apart. I finally could get in the middle and literally had to choke my dogs with their collars to get them to drop the little thing. It was absolutely traumatizing. I was screaming so loud I peed - there was blood - the little dog was yelping. It was absolutely horrible. I still cannot even look at my dogs I am so disgusted at them. I don't know if the small dog made it, although he ran away, it seemed my dogs really hurt it. I don't know where he lives. My dogs have never done this - and I never thought them to be aggressive. I don't know if they thought the little dog was prey and they acted like a pack - or if they are just horrible mean dogs. What do you think I should do?
