I guess you have not seen HoneyB the episode of the Golden Lab on Caesar that is food aggressive, seriously not good and savaged his hand and arm. Would I then say labs are dangerous, no. Judge the deed and not the breed
My staff was a competition flyball dog and very successful it all changed when she was attacked twice on two occasions and it all went pear shaped. She is kept on lead and wears her yellow dog high vis coat stating " I need space" sadly it does not detract those owners with dogs that just are off lead. I do my bit as a responsible owner. If my girl is introduced to other dogs in a supervised manner and controlled, it's ok, out of control dogs it's an issue
I bought a lab puppy, they are now BFF and best thing I ever did. She is happy, calm and content, but I never take it for granted with other dogs.
Look up Wallace the Pitt or Jambo the Trick Staffie, many of these type are also PAT dogs and a staffie has been the latest recruit into the police force as a sniffer dog. A percentage of dogs in all breed types are susceptible to biting, however the difference is clearly the power to cause more damage than others.
Take the case of the rescue staff pup, abused, starved and near death. Rescued and brought back to full health, trained and socialised and a very happy dog. It was reported to the police purely based on its look, the dog was taken away, its breed could not be 100% clear even though it had done nothing wrong but be abused by humans it was destroyed after its short and unhappy start in life
Please try and see beyond the media hype, as I said at the begining judge the deed and not the breed a lot of innocent dogs are losing their life because of the way they look
