Fantastic product, fantastic customer service. My dog unfortunately gave me the chance to test the replacement policy shortly after I received my leash. (This is not a testament to the quality of the leash, rather to my dog’s ability to chew through anything once he puts his mind to it). MD got a new leash in the mail quickly with no questions asked. Can’t say enough about their service, they really take care of you. I have a feeling many of my friends’ dogs will find themselves at the end of an MD leash really soon!
