Usually we run in the mornings when it is still cool out; however, one time I didn't have a chance to run until around 1 p.m. It had gotten quite warm, and it really wore Skipper out. He just laid on the dining room floor and panted and panted and panted some more!!
We have been easing into our running. Next week will be our first week running more than 2 miles without any walking. I think it will be tough for both of us.
I have a running log online. You're welcome to check out my progress. Here is a link:
I update this log after each run. It's a great tool for me.
