Has anyone here tried the thundershirt for a dog with leash reactivity? My young one, Dan is so excitable. He pulls, is generally distracted, and is reactive towards dogs and anything he finds unusual or scary. We are working hard on focus exercises, positive reinforcement for good behavior, and trying to find low distraction environments. However we live downtown and any potty break has to happen in a high commotion environment. It is hard to even find behavior to reinforce sometimes. I have no experience with the thundershirt but I wonder if it would help calm him enough to do some more productive training. Any thoughts?
