My husband and I highly recommend Hal! Our dog Ivy had some issues with resource guarding, always tried to run out the front door and pulled a lot when walking on the leash. By the end of the first session he had her heeling while we walked her and eliminated the pulling!! She is no longer a flight risk out the front door and he gave us the tools to continue working with her on the resource guarding. (Her guarding things has improved DRASTICALLY since starting with Hal!). Overall, we are thrilled with the results!
