Anyone out there run with their dogs? I've started running with my beast, but she nearly dislocates my shoulder every three minutes stopping to smell something. The vet suggested a belt-style leash (and more training). Dottie is about 40 pounds. My first question is whether it throws off your gait. A number of models I've seen have other accessories, like water bottles. Are these useful or just bulky? We're running about a mile now, aiming for about 3 miles. Thanks!
I've run with my dogs and have learned three key things: 1) there is no easy way to run with them without messing up your gait, 2) you really have to work with your dogs to train them to only stop when you say so (not just because they smell something interesting), and 3) it is an awesome experience to see them excited to run with you, thus making it so worth the effort of dealing with a messed up gait and training them. I loved doing it until they got too old to run. But regardless of what kind of a leashing system you use (I've tried several), it's pretty hard to get into a steady gait for any period of time - it's just hard... But the joy of running with them is awesome.
Here's a blog post with some pictures of one of my dog runs... http://runningthrutime.blogspot.com/2013/04/dog-running.html
