flaming hell- the thing that stood out the most for me in the OP was a 7yo, unsupervised in a beer garden, being allowed to approach, and then HIT and then CLIMB onto an unsupervised dog- where the hell were the parents?? Too busy pissing up to notice what their offspring was up to?
Yes, it is never ideal for a dog to be out unsupervised, but mistakes happen. Dogs get out. I've known many many responsibly-owned dogs (including my own
) managing an escape bid. Obviously the DH is responsible for that, BUT he didn't let it out deliberately! whereas child with stick behaved deliberately and feckless parents either sat supping and watched OR were oblivious, which to me is a far more disturbing lack of responsibility.
I've had an unsupervised dog appear in my garden. I approached the dog first, tried to find out who it belonged to. Told dc (well-accustomed to dogs) to leave it alone. It's not rocket science. There will be "dangers" that arise, and as a parent it is YOUR job to ensure that your child is safe and supervised.
And WHY do people persist, despite the proclamations of those of us who routinely work with and know dogs, in believing that SBTs are a "vicious breed"? As a vet of 16 years, I can categorically state that I have never met a staff I am wary of. OK, some of them are not great with other dogs, but they are definitely not anywhere near the top of my list of dogs to watch when it comes to human-aggression. I realise I am wasting my time in this, as the DM and its ilk have far more experience and knowledge than I do....
As for your concern re the DDA, OP, the fact that there were several witnesses who didn't see the dog as "threatening" and that the police brought it home should mean that you can relax somewhat. For my part, I have found the police less than zealous re the DDA, even when there ARE grounds for action!! I reported a rottie, an akita and a SBT running wild, in my garden, to the police. The three dogs came in and half-chewed their way through my poor rabbits' hutch, and appeared in my garden on several occasions. Apparently the police could do nothing, and the dog warden was too busy. I gave my concerns that I, at the time, had 3 children under 5, but tough shit. I had to pay thousands to get my garden totally fenced in, AS A RESPONSIBLE PARENT, to ensure my kids weren't caught between bunnies and dogs. police weren't interested, despite other people having previously complained. In fact police suggested I "put something down"!!!
When asked if they realised this would be illegal (not to mention dangerous to MY dogs and children), they hummed and hawed. I wouldn't worry too much. If completely irresponsible owners can get away with it on a regular basis (which I am NOT saying is right!!) then a family pet, provoked into nipping ,observed by several witnesses should be ok.
And I am NOT a "dog apologist", because the DOG has nothing to apologise for!!
