Alright then, let's use it for educational purposes. The scenario in the pictures - calm, friendly dog approaches baby that it knows, under adult supervision - is not a typical scenario for a dog bite. Nonetheless, dogs and babies should always be supervised.
A recent US study found that the most common scenario for children under 7 getting bitten is when the child approaches a dog at home (the dogs home, regardless of where the child lives), and the dog is stationary e.g. laying down or standing still. So young children should not be allowed to approach a dog that is lying down or stationary. If they want to pet the dog, they should call it over to them. As they get older, they should be taught this. Also, some dog bites occur when an adult thinks they are supervising but they weren't really - i.e. they were in the same room but doing something else, such as watching TV or preparing food, and not watching the dog & baby at the time. If you can't supervise, you need to separate them by using a pet gate or dog crate or door etc.
Another recent study found that many parents and children do not know much about preventing dog bites, and would welcome more information about it.
Sophia Yin has some great material about how children and dogs should interact. I seem to be forever posting it, but for those that haven't seen it yet, you could start here. The Blue Dog project used to have some good stuff too, but unfortunately whenever I look lately they say they are updating their website.
I don't mind cuebill's first post because she meant well. But can we be light-hearted again now please? After all, if we can't have fun with our dogs, no one would have them and they'd all need to be rehomed.
