1- eager mutt (ours is called Ri and she is always ready for a run; even when we aren't up for it!)
1- rock climbing carabiner
(found at your favoriate outdoor gear outlet store; we use a 'locking' style but it's not necessary)
1- regular dog leash (i'm guessing you have a couple around the house already but for this setup a 3-4' leash is best fit)
1- rock climbing sling
(found at your favoriate outdoor gear outlet store; size matters as the appropriate length is crucial to achieve a best fit more on this later- see step 3 on how to size)
1- poop bag...while Ri dosen't usually go on the run we are always prepared to pick up and carry out
1- an eager dog owner usually helps too!
