In my opinion bruising isn't a soft bite. However, I agree with PPs that said the kid is riling up the dog and the dog is playing - kid needs to be taught to play more calmly with dog. Not all dogs can handle certain kinds of play without getting over enthusiastic.

teach child and dog to play differently -- like fetch.
