Since I've started running outside (rather than on the treadmill at the gym) I take the pups with me sometimes. Today we hiked for an hour then ran 4 miles (with dogs on leash) afterward. I do stop about every mile or so and let them get in the water for a minute, so not continuous running for me. I usually take them the last few miles when I want a reason to stop for a minute here and there! Also, who wants to come home after a run and have two crazy dogs wanting their attention?
