My two year old golden retriever, Roxy, is a doll but she just did not listen. Her attention span was nil. I investigated training services and came up with K-9 University. Because of Roxy's poor attention span, it was recommended that she spend a week at the University (living there) to learn how to listen. It took actually 10 days but when I got there, she would heel and walk and not run off, listen when I told her to and she and I were both much happier.
