Here's a quick instructional video that details how to make a drag leash for your dog. Drag leashes are incredibly functional for raising puppies, training a new foster or rescue, and for having a built in indicator for when your dog is completely ready for true off leash behavior.
I have also recently joined Twitter. So if you want to follow @Dogman_Moran you can see all my daily musings on dogs, bicycles, beer, and anything else I find interesting. Its apparently a great place to ask questions.
