I have two dogs. The little one is about 60 lbs and great with everyone unless it is just women home, then dont come in if you are a guy. My other one is a doberman. Great big sweet dog. Looks mean and is very protective if someone is not suppose to be here. Anyway, in the fall we usually have mice get into the house so we set out traps. Well I set out a couple where I did not think the dogs could get to. They did now I cant get either one of them to go upstairs. They are scared to death of mouse traps. Another one snapped with a mouse in it, upstairs, you can barley hear it from here and both dogs ran under my desk. Actually kinda funny, poor dogs. They werent hurt at all. I just noticed them acting funny and two traps snapped with nothing in them.
