Buddy could walk forever! He's a larger Yorkie and loves being out doors.
Two things I thought Yorkies didn't like to do which is one of the reasons
I picked this breed. LOL
I walk Buddy 4 times daily. The 6 and 8 am walk is only about 15mins the
5:30 walk is about 1/2 hr and about 1mi, the longest of the four times
he goes out. When it's time to go home he will sit and not budge looking
in the oppistie direction hoping to go back that way.

I can't fool him.
He knows every which way is home. He would be very happy running
and being outdoors even in cold weather this boy of mine would.
