I believe that it is up to dog owners to keep their dogs under control in public places (actually it is not just my belief, it is the law). Every week on here someone is posting about how their dog has been brutally attacked while running loose in parks and loads of peolple jump on crying "how terrible, glad your wee baby is ok/gets well soon". I believe that people should take a close look at their own behaviour and dog control before accusing anyone else. It is all about responsibility. I would have no hesitation in sinking my boot in any dog that is a threat to mine - and before anyone calls me cruel or uncaring - it is because I care about mine.That would mean no-one could ever let a whippet off lead except in a dog park on its own....... :-In my experience it is wrong to always assume that strange dogs will be friendly. Ok, we have all watched the Dog Whisperer and feel that we know our own dogs and can read the body language of other dogs..........until the s"&t hits the fan and a dog/person gets injured. If your dog is not responding to recall and is out of your reach/not on a lead where it is under control, causing annoyance to other people/dogs I believe the owner is not being responsible.
