And so this particular debate rolls on. Our opinion is that any dog in the wrong hands or environment has the potential to become aggressive and therefore dangerous. This is not limited to breeds banned in the UK although the role of behavioural morphology cannot be ignored. In short we have tinkered with dogs to produce dogs for a purpose, for example border collies for herding. Some breeds were created to fight or guard and as a result have unfaltering determination, very high pain thresholds, an altered prey sequence whereby there is no warning that an attack is pending (such as growling as it would give the game away) and a muscular physique. It is not the dogs fault, the blame lays with us and there is no easy answer :( bear in mind that it is the dachshund that tops many surveys for bite frequency and not the breeds that many would suspect!
Despite what the article says, it is a myth that terriers can "lock their jaws". They can't!
