What a remarkable difference in my dachshund within the first two hour session! Walker has some aggression issues as well as pulling on the leash, barking and growling, jumping up on people, and crowding the door way. He also has some marking habits that we are looking forward to breaking (we think this has to do with him thinking he is in charge). In the first session Walker was able to walk loosely on a leash and follow commands to wait for me to go through a door first. Walker has also improved on letting visitors in to the house without barking/growling/jumping and violating their space. Our next session we are going to work on his aggression towards other dogs while on a leash. We ended up signing up for a year long guarantee. We were given homework to work on for ourselves and Walker that we will be working on daily. I can't wait to see what the future sessions hold and look forward to learning more about how to communicate with my four legged friend.
