I definitely agree that there are way too many irresponsible owners out there.
A postwoman was very seriously bitten by a neighbour's Golden Retriever, her hand was bitten to the bone in several places, and torn and lacerated as the poor postwoman was trying to tear her hand away , causing the Retriever to pull back.
The poor postwoman needed lots of surgery on her hand {I was a witness, so we gave her first aid and another neighbour took her to hospital}
Labradors and plenty of other breeds can be a bite risk.
when walking one's dog, it's often possible to tell what the dodgy dogs are.
It's LOVELY when owners are responsible, when they clip their dog onto it's leash when they see one approaching, and of course, I do the same and give each other a wide berth.
My dog is gentle and quiet, and because of this she can get bullied and harassed by other dogs.
Our Mum was knocked over by large dogs on Sheen Common and the 'Walkers' did nothing. She was so frightened.
