Someone sent in a question asking how to clean a dog collar. I used to have to wash my dogs collars leashes more often when my dog was younger (she is 14 years old now and doesn’t run much these days ). When she was younger we would go for a trail run a couple times a week and she would love getting all muddy. I used to have a small mesh bag that I would place the leash in the bag and just launder with my regular laundry, as long as it was a heavy load like towels. that way the metal part of the leash would rub up against the washer drum. I would just hang the leather dog collars to dry.
It always worked for me, somes my dog would get into some pretyy stinky stuff out on the trails. You got to love dogs!
