I have 2 questions 1. I read in books and web pages that ABD's become "couch hounds" around the age of 2 or so is this true?? My ABD is almost 3 and she acts like a 100 LB puppy. 2. I know ABD's are very hard headed and stubborn but someday's i tell her no or give her a command that i know she knows and she'll just look at me stupid and walk away. Any of you have the same problem?
