I contacted Donna because my 9-month-old Coton was constantly yapping at everything outside and inside the house. He was restless and driving me crazy. I could not let him greet people because I wasn't sure what he was going to do, and he had to be crated if had children visiting my house. He was also pulling on the leash and I felt embarrassed taking him for a walk due to his aggressive barking at people. We had done some basic puppy training based on operant conditioning (rewarding the dog with a treat) with him elsewhere so the dog knew the basics. However, it wasn't until Donna got here when the he understood what was really expected of him. After a two-hour session with Donna the barking, pulling and ambivalent behavior was gone. And this was all accomplished without the treats, which I found a lot more convenient and natural for me. The next day after Donna's visit I wasn't sure if the dog was sick because he was so peaceful. He wasn't sick. He simply knew what was his role now. I was the alpha in the house, not him. I would protect the house so that the dog didn't have to do it. The yapping, pulling, aggressive and otherwise ambivalent behavior around strangers and children was gone. When someone knocks at the door now, he knows that he's not supposed to bark and run to the door but he'll wait and do what is expected of him. I believe that dogs do well if they can. Before Donna got here my dog couldn't. Donna gave me the dog I always wanted. I highly recommend her. Thank you so much!
