I really can't decide if some people are being deliberately hard of thinking here?!
If you are a parent of a child who may go home with school friends, is it safer for your child if they are taught to ask 'do you have a dog at home, will your parent be at home when we get there' and if the answer is 'yes' and 'no'... say 'I won't come home with you today'.
Or is it safer not to bother teaching them that dogs unsupervised by adults may be a danger?
I don't believe that that simple action will save ALL children, for a start many cases involved children too young to do that, and children for whom adults were present - but it is hardly a difficult thing to teach ages 8+ is it?
But my main point is not that we teach children to avoid being killed by dogs - its that we teach children to hopefully avoid them/their relatives OWNING dangerous dogs.
Btw the last few cases of dog related death involved:
XL American Bulldog (not a pitbull)
Chow x GSD (not a pitbull)
Cane Corso (not a pitbull)
Rottweiler (not a pitbull)
Husky/malamute type (not a pitbull)
Bulldog (seized by police, put into kennels so they'd have made a statement if it was an illegal breed)
But yes lets keep shouting about pitbulls - that will obviously solve the issue.
I have no particularly strong feelings about pitbulls either way, I have worked with some lovely ones, I have met some distinctly unlovely ones who I believe were that way as a combination of poor genetics and horrific handling/training.
I can say the same about most breeds I have worked with though - but the most dangerous dog I ever worked with was a spaniel x golden retriever, who would bite repeatedly, without warning (those warnings having been beaten out of him early on), over a trigger no one could see (guarding bits of fluff or tissues or even a smelly patch of floor!). He was, at my recommendation and the agreement of the rescue, euthanised.
I do believe that focus on 'illegal breeds' is a misdirection, it isn't helping anyone fix the problem - people behaving irresponsibly in a variety of ways, with an animal capable of inflicting injury and in some cases, of killing.
