I can totally relate to the 'banging your head of a brick wall' feeling. I feel like a parrot repeating the same thing over and over and getting now where. I am so sorry to hear about the poor child getting mauled, even if it does prove that any breed can be a culprit it pains me to hear of a child paying the price of an adults negligence, negligence caused because people have been given this 'good' dog 'bad' dog list ie. if your dog is on the restricted list its a 'bad' dog but if its not its a 'good' dog and therefore ok to leave with children.
I am in the lucky position in that I've never been bitten despite having dogs for 30 years. As a child my dad bred and trained GSDs and dobermen for security and I was always taught to have respect for dogs, not to pull out of them, not to touch their food etc., skills alot of children aren't taught.
I've had restricted breeds of my own for the past 16 years who I train and socialise with avengance, my dogs will literally shadow me whenever I go out for the first year and then as much as possible after that. The interesting thing I've noticed in the last week since I've started putting a dogmatic collar on my Rottie is not no one stops to complìment her anymore as they precieve it to be a muzzle and therefore that she is vicious which make me sad because she doens't understand why people don't stop to rub her anymore, how can this beneift socialising a dog???
