Running with a puppy

So my extremely rambunctious puppy has gotten me running every night just to wear her out. We are slowly building to 5-miles (read SLOWLY). Turns out though, nine month old puppies dont really want to run unless they are chasing things, eating things, trying to hop on bicycles, trying to jump on their owner, etc. etc. Fortunately I don't have to plan any sprints, izzy adds them in whenever she sees a cat/squirrel/car/person/stroller/dog/leaves blowing in the wind/anything moving. Hey at least I am running(and a lot faster with a dog dragging me)!
