Patrick was great! We definitely recommend Bark Busters. Colby, our Maltepoo, was so aggressive we were ready to put him down. In two hours, one Bark Buster lesson, we saw an amazing difference in him. Thank you Patrick! Our whole family is happy and Colby is better behaved. Not only did our vet recommend Bark Busters, but so did Petco when we explained Colby's aggressive behavior!
