There are a lot of misconceptions about playing tug with your dog. In my experience, (and lots of other trainers I respect) as long as you teach your dog some ground rules, tug is a great way to condition your dog to have a soft mouth as well as providing your dog exercise.

I frequently get questions about dog play, whether it is between two siblings in the same home or about a dog that frequents the dog park and plays with other dogs. The questions might pertain to my client's dog and if their play style is too rough or worries about the behavior of other dogs at the park.
This morning I took my three dogs, Ranger, Trooper and Linus to the park. This is a necessity since I have two Collies and a Sheltie and live in Chicago. Until someone moves in with a flock of sheep to keep them busy, it is my responsibility to provide them with a heavy dose of physical and mental stimulation. So, I took them to a park near my house and played Frisbee with them and threw the Kong on a rope. As usual I also worked on training to keep them sharp. I asked them to stop, come, go left, go right, finish, stay, etc. They had a lot of fun and were their normal goofy, wonderful selves.
