Since we adopted Max, our 16-month-old schnauzer, we decided he was the best dog ever...smart...playful...lovable. However, the only bad habit was barking when someone came in the house and didn't stop until they left. After many months of trying everything, our vet recommended Bark Busters. Are we glad she did. As soon as Jack came in the house, he knew exactly what the problem was and within 10 minutes had Max under control. This was 2 weeks ago and he has been the perfect dog...no barking...that we knew he was!!! Thanks Jack...You are the best!!!!
