I have a 12 week male Papillon and he is extremely smart. He is one of the smartest animals I have ever lived with (including a corgi and border collie - and they were SMART!). I have been told to look into agility classes for him but I have some concerns. He is 2.7 lbs now and will only be about 6 lbs full grown. He is VERY fast, agile and listens intently but I have always seen larger breeds in agility (border collies, shelties and the smallest I have ever seen was a jack russell). Then again I have not seen many agility trials - only a few on TV. Has anyone ever owned or known of a Pap that did agility? I thank you for whatever info you might have..... oh, and little Domino thanks you as well!
