I agree this situation is not good.
the dog should have been on a lead and under the owners control.
the dog could react to many things that could cause it to bite.
Huntso has some good pionts but really with the information given about 1 bite you are ready to condemn the dog whose owner did not have under control, and then compare it to a dog that savaged someone
I fully understand also protecting our kids but to punch a dog that has nipped someone does not teach it not to nip, it will only make the problem worse. a dog needs to learn behaviours through reward and discipline not through fear.
As for wanting to put down all rescued dogs, well that is a very uninformed statement.
The problem with bikes as I learnt from being a postman back in Australia, where we ride small motorbikes from house to house is that it is a hard thing to teach a dog not to chase. The dog is distrustful of the bike because it moves relatively quickly and is noisy, dog barks or chases bike to protect its house/yard etc. we deliver mail in box then ride off. To the dog he has been successful as we have ridden away and he takes the credit. Its teaching him a negative behaviour but there is no way round it without spending time with the owner and dog.
A lot of this stuff is taken as malice and viciousness rather than looking at the behaviour. Dont get me wrong I have had more than my share of dog bites from some real bastards but its working out why and then fixing it, and yaeh there are some dogs that are dangerous and the best thing is to put them down its just that this doesnt sound like one.
And I know whats bites are like mate, if you think dogs are bad try working with seals, I got bite last Saturday, chomped down on my left index finger into the knuckle. Antibiotics for the next two weeks as well so I can sympathise.
Take care and ride as best you can.
Carlsberg dont build Singlespeeds but if they did.......they would probably look just like mine.
I've spent half my life on bikes.........the other half I wasted
