Maggie chases them too. She has gotten close to getting one before but I really don't know what she would do if she caught one as the squirrel is her size, LOL. I bought her a squirrel toy as well but I don't think she knows what it is either. Sadie however likes to pull the hair off it's tail. That toy that Kay posted is so cool. I am gonna have to look into getting one for my 2. Maximus maybe we can get you and some other PT dogs together for a squirrel hunt....Maybe a group effort could tackle the squirrel problem, LOL.
