Thanks for the update, sounds reasonable about a pulling dog and 10 yo tugging him back. I once had a pack of 3, all walked at the same time, all pullers, I could never train them out of pulling, this was years back, before there was any training advise on the correct way of training a dog to not pull. Neutering him now at 5 yo I don't believe will stop his behavior, it has become a habit now. Taking to the children IMO is good idea, train the children on how to walk a pulling dog. Removing his harness after each walk is the best thing to do, the harness could be rubbing his skin irritating him after a walk of pulling. Good luck with speaking with the children, I think showing them the pictures of the bruise will help the children realize how sensitive his skin is and will help when they have to walk him.
