How to ensure your children don't get bitten by a dog.

Tell them not to go up to it.


Sounds a bit glib I know, but that is all there is to it. 


If you want to interact with a dog, even if it lives with you, always, but always, call it over to you. If it doesn't come there's nothing lost - if you go up to it, all sorts of issues can arise, it may just be that it's taken by surprise - in any case it's not worth the risk. 


If it's on a lead, then it's more than likely to be unhappy to be approached as it cannot assess for itself what to do. Putting a dog on a lead removes its ability to run away if frightened, so it's no surprise that, if unsure, it's going to give a "warning shot" - and that's usually with the teeth. It's all they have. If it doesn't you're lucky, but it's still going to be uncomfortable with an uninvited approach, after all, wouldn't you?


Simples!
