Oh yeah, good idea on the collar. I used to have to soak Jet's nylon collar in a jar of Pine Sol for a couple of hours. Then I would put it in a work sock, into the washer and then into the dryer. And that was more of a sweaty smell. Jet wore her collar all the time. I no longer leave the collar on all the time and I now have a waterproof one, but left on all the time I think it might still get stinky.
