Thanks for sharing. I appreciate knowing that I'm not the only one who has a dog who seems to go absolutely beserk at the sight of a cat!!! And it's strange how he seems to be so violent towards them. He was a stray for a while. Maybe that influenced his behavior? I have no idea! Duncan is very well behaved most of the time but cats, squirrels and the occasional rabbit that we see on our morning walk and he just seems to lose all control of himself! He doesn't listen to me at all. In fact, it's like I've disappeared! On the way to the park, there are about 2 houses where cats live and he has seen them there before. He STILL remembers and gets all excited and looks down there driveway looking for them again! WEIRD!!
