It's the truth! They can train ANY dog! We rescued 2 boxers who were absolutely uncontrollable. In fact, it didn't look like we were going to be able to keep them both but Karen worked very patiently with us and you wouldn't believe the difference. All our family and friends are so amazed at how wonderfully well behaved they are now. What we learned has even helped us around other people's misbehaving dogs! I can't thank Karen enough for helping us to have a happy peaceful home with two very sweet dogs.
