There was a small dog (Jack Russell sort of size) tied up at the school gate and a probably three year old boy was running ahead past the stream of people slowly filtering in to the school, then the boy went bounding up to the dog "hello doggy, hello doggy" - the mum was too far behind to grab him.
It all happened really quickly, but in slow motion IYKWIM, and when he got to the dog (who was kind of ducking by now) the boy threw his hand out to it's face. Luckily for all the dog just did a snappy sort of snarl, enough for the boy to pull back a bit quick, but didn't connect.
I've just been thinking, what if that dog had nipped him, or even bitten him hard, I wonder if anyone would have spoken up for the dog?
