I run with my two all the time; I am limited by the fact they are only 5 months old, but I follow what I read on this forum (5 minutes of running per month of life, so I'm at 25 minutes of running). Like Sschoe2 said, they like to dart in front of me at the beginning of every run because they're so excited and they like to attack each other in front of me, also because they're a bit overexcited. But they settle down after 1/2 a kilometer, and then it's great! They love it and I love it! Can hardly wait until they are grown and we can have long, leisurely runs together and not have to make sure they're not running further than is good for them
