Bandit (2 1/2 years) and Nala (6 months) will walk around a circle we have in our neighborhood which is four miles. When Nala was a young puppy she could only do a block or two at a time, and then had to be carried for a block or two. Now that she's a "grown-up-puppy" she can make it around the circle. They are both tired afterwards and seem to really enjoy it. During the summer and fall months we do it a lot...especially on 3 day weekends from school

Bandit is also a CHAMP at sleeping though!
