We brought Penny, a six month old German Shepherd mix puppy that we rescued from a shelter, into a household with our rambunctious four month old goldendoodle, Abby, who already thought she was the boss of the house. We thought it would be good for Abby to have a sister. By the second day at home, both pups were out of control - one picking up the bad behavior of the other - barking, digging, jumping, and biting. Penny was acting like a bully towards Abby and Abby's biting was out of control. We had to keep both dogs separated and we were so afraid we might have to take our new puppy back to the shelter or find her another home. I decided to call Bark Busters to see if they could help. Kathy and Betsy explained everything to us and then we went to work with Abby and Penny. What a difference! The techniques work great! The house is much calmer now and we now have two well-behaved dogs that play together without a referee! We can't thank Kathy and Betsy enough for their help.
