I've heard various things about when it is ok to start running with a dog. I even bought a book, "Running with Man's Best Friend" but I'm still uncertain.
The Border Collie needs lots of exercise. Lucky is almost 6 months old. I take him for a long walk almost everyday and hikes in the woods on the weekend. When we are out on the trail, he often runs...I've been starting to run a little when he does -- mainly just some short sprints.
I don't want him to hurt himself and wonder if the usual advice (1 year?) doesn't apply to this breed.
I used to run 5-6 miles per day but now I'm just walking with the dog waiting until he's ready. I'm anxious to run more but don't want to hurt him.
