Rabbits, too. They drive the dog crazy and eat the bark off the birch. If I say rabbit, even indoors, the dog puts his ears back and starts looking all around.

Hah, we had the same problem with deer around my parents house. Whenever I said Deer, my dog would get all excited and start looking around for one to chase. She chased a lot of them and they would always run away and she would not catch them. One morning I called for her and heard her yelping and growling. I found her running in circles just inside the woods and couldn't figure out why. I called her and she came bolting out into the yard and a doe came chasing after her. The deer was about 15 feet from me when I shouted at it and it looked up, saw me and then bolted back into the woods. I don't think my Collie likes to chase deer anymore.
