Brenda Des Moines, IA 9/21/2009 12:08:25 AM I've also owned several different breeds, and the Rat Terrier is one of the best breeds I have owned. I have 3, and they are just a joy to have. There is a misconception out there that they have such a high prey drive that you can't have them off leash or they will run off chasing a rabbit, squirrel, etc. My dogs, all from different bloodlines, have proven that theory wrong. They ALWAYS come when I call them. They are that eager to please me.
