I Love Ceasar Milan, I have his DVD and I've seen every episode of his Show and I would like to go to one of his Seminars, if I ever got a chance to go? B/c they are all booked solid for up to a year in advance!
I walk my Pack of 3 Yorkies, twice a day for 30-45 min. depending on my schedule? One walk is done off-leash @ the Dog Park where they do what they want (within reason and safety of course) and their evening walk is on-leash around the Neighborhood or our Local Lake/Pond. I think it's very important!
But he has admitted on every episode that had a Yorkie on it that they are more difficult b/c of their size and ego, compared to a larger dog. I think his "Strong Arm" techniques work better on other Breeds. I do follow his formula of; Discipline before Affection. I don't have any problems with mine and they are a 3 yr. old male, Artie and a 2 yr. old female, Abigail and their female baby Tiffany Aloha w/c is 8 mos. old. Good Luck!
