We've been taking walks everyday.  They are usually about 1.5 miles, around 1/2 an hour.   We try to go twice a day. He loves it.  He does very well on the leash.

 

 

 

In the video he is a little less focused than usual because we are walking behind my son riding in the wagon.  He normally walks pretty nicely right next to me.

 

I am no professional but it seems to me that his leg is better when we get more exercise.  His limp seems more pronounced when I have not taken him for regular walks, but even then it is not  bad.
