+1 for Andies comment.
On the Pennine Way in a farmyard on the walk I was nipped by a dog, one of three sheepdogs that surrounded me. I knocked on the Farm door; the guy said it couldn't have been one of mine they never bother anybody. I said do I look like someone who would inflict a wound and make all this up. Cue half mile later for cleaning session on leg and antiseptic.
When I got to civilisation I reported it to the police.Yes it could have been on a child.
