Love this company. I recently adopted a Dobe who is 13 months old and a handful. Wonderful breed, but full of energy when young. I just spent $ 3,000 on professional training with someone in San Francisco with hardly any result. I searched and found That’s My Dog and within 1 week I had done more than I ever thought I could do. Their DVD’s are full of information that gets results immediately. TMD website has great videos as well. YouTube channel has more extensive training. I was able to get my girl to be off-leash in a national dog park within 1 week with perfect recall. Obedience training is a snap, learning new tasks at the rate of 2 per week. Highly recommended!
