I think it's a great idea to run with your Yorkie. You may want to work up to the 3 miles. I used to run with my Westie and he loved it. We kind of went out of shape together during the long New England winters, and so we'd gradually work up to our 4 miles. Unfortunately, we're both very out of shape as we didn't run much last year. I'm not sure if I can take him out running now, as he's a bit over weight ... perhaps a walk/run session to work up to 2 miles may be in our future.

Now, Trixie who is 6 months, I would take it easy with as well. She's full of energy too, but we did a practice 1 mile run the other day and she seemed to do great with it, but she was totally wiped out when we returned (slept for a few hrs). So, I may take her out for a 1/2 mile next time.

Good luck with your running buddy!
