Thanks all! :)
Marge, I have 3 large dogs (see profile). And 2 children. And, as I said, have had dogs, including the breeds people claim are "dangerous", since the DC were born.
MY dogs will go nuts at you at the fence. Or at least 2 of the 3 will. The one that won't? Not the Labrador, but the biggest German Shepherd. They are also perfectly well behaved, friendly dogs and no threat (unless you are threatening me, in which case my LABRADOR will have something to say about it!).
Mine are trained not to chase rabbits/chickens/pheasants etc whilst we are out walking (I live in the country). However I couldn't guarantee that they would act like this when not under my supervision.
that does NOT mean that they or ANY dog is a natural or automatic risk to you or your DC. I work with all manner of dogs, some of which are dog and/or cat aggressive. ALL of these are VERY human friendly. I'm not saying this will ALWAYS be the case but that other-animal aggression in dogs and human-aggression in dogs are NOT naturally connected.
My kids work with these dogs in rescue too, btw. :)
Now I really MUST run, thanks again for the kind wishes ladies.
