So I have a question....I run about 2 miles a day trying to loose my post baby belly even though my son is 3

and I see these girls running with there GIANT dogs like lads and retrievers so I was wondering can you run with you little dog??? I know my Bella is too small but Tibbs is getting bigger he is 6lbs now....So I was just wondering if any of you do or even if you can run with your Yorkie?
