Our dog, Nessie, is a rescue dog. She was found in a field and is approx. 1 year and 3 months. Since nobody took care of her, we have quite a bit of work training wise. She is pretty reactive and pulls a lot while on a lead, but loves walks. We have been making great progress with her in the past two months we've had her; someone at our local dog park recommendend us to try a PerfectFit harness for pulling. It has made a wolrd of a difference when she sees other dogs she reacts to. We can clip her front and back and confidently hold her until she calms down. The padded harness and the way the lead connects assures us she will not get hurt. Both me and my husbad love the harness and lead. Jen from customer service was extremly helpful and prompt in helping us pick the correct size as Nessie is a mongrel. We will pass the recommendation on to everyone.
