I myself am a marathon runner. I have two yorkies that are about 5 pounds each and the LOVE to come running with me. I was wondering if there are any others who take their babies running with them, and how far do you go.? This morning I took them out for 4 miles, and they kept up the whole time with me. I realize 5 pounds is a small dog, but the amount of comments and laughs I get from people I pass by on the bike trails is ridiculous. Have they never seen dogs go running before?! Anyways, just wondering if there were any others out there that can relate to us!
