I have to keep Brody's leash on even when we play fetch as, although he seems to have a good recall, I never know with him, so, better safe than sorry. Anyway, the leash always gets wet, either because of rain or dew, so I have to hang them up to dry. They are starting to smell really bad and I have sprayed with Febreeze and the new Lysol fabric spray, but the rank wet doggy smell still comes through. I am worried about putting them in the washer because of the heavy metal part. Has anyone done this, or is there something I can soak them in to get rid of the smell?
