Doggy Dan may be good at what he does, but the four free video's for email sign-up promised were just infomercial vids with maybe about one minute total in all of them put together. Around the 3rd video he gives a hint of 'long leash / short leash' training that to me is uncalled for and borderline negative training to keep your dog mindful of establishing boundaries outside and in -- that in itself made me not want to listen to him any further (and for a monthly fee, I can only imagine what other damaging techniques he would make other owners cause harm to their dog. In my opinion I would say use extreme caution. Look in 'tips' section for exact weblink to vid I'm speaking of. Offer me makes:
