I cannot say how pleased my family and I are with Bark Busters. When CoCo came home with my husband and I, CoCo had lots of behavioral problems due to the environment he came from. We spent many sleepless nights going through torn shoes,some aggressiveness and him digging through trash cans. CoCo did what ever he wanted. The day that Jim came to our home and showed my family and I that it was about being the leader of the pack. CoCo was the type of puppy who constantly nipped and bugged at you. I won't forget after Jim left from our first session of training, we were able to sleep. Everything Jim showed me worked with Coco. After my husband returned from being in San Diego, he came home to a completely different CoCo. Now, our little boo-boo sleeps through the night, he does not jump or bite, he does not dig so much through the trash. We are able to enjoy our little bundle of love.
