I don't agree with that @Hearhere I'm sure if a dog was being dragged around, hit, antagonised by an adult man..the dog would bite, that is the one of the only ways a dog can protect itself.
Like if a cat was being antagonised the cat will scratch the hell out of you and bite you. Every animal has a way they see of defending themselves.
We worked very hard to make sure our dogs are well trained, and got so much useful information from a dog behavioural specialist.
Pecking order is crucial.
That's why even though my dogs had been around many children, when we did have children and my toddler started to crawl, walk etc..we knew the appropriate work that needed to be done, so that our dogs see our children above them in the pecking order. As it's completely different a new little human suddenly coming into our home.
I don't know after all the work we have put into our dogs, whether if I was to drag my dog around, hit it etc, if it would bite me or not..I have never tried and wouldn't be so cruel to attempt it.
Of course on the face of it, the suggestions of chipping etc by @Hearhere and other posters and my suggestions of mandatory dog training lessons, all at the expensive of the dog owner, along with all the other suggestions made by me and others, would no doubt reduce incidents happening..but I do understand that it's more complex than this to put into place..and that is why we are all so invested in this thread..to work out, how these suggestions could be made to work.
