Hi Secretplace - I don't know if cherie is speaking about me but I was the surgeon working in A&E sewing up dogbites.
I can't say specifically if people were lying, but honestly, the only two phrases/stories which were repeating again and again and again were 'they were only left alone for a moment' and 'they've never done anything like this before.' Were the people lying, again, not sure, but often the stories were corroborated by their family/friends who came with them. Shock, surprise and almost...betrayal was often the feeling. That their trusted, loving family pet could do such a thing.
The particularly awful staffie bite I assisted (plastic surgeon had to be called in it was so bad) sewing up on a toddlers ear was a staffie where the gate was opened to let the staffie walk down their path to get into their car, it broke free of the owner, raced down the path and grabbed hold of a toddlers face. Entirely unprovoked.
Entirely unpreventable? possibly, had the dog been muzzled, or had the owner had a grip on it's collar. But it was a split second thing and I don't think it could have been predicted.
But I wouldn't single out staffies. I'd say it of all dogs - labs, GRT, collies, anything. The bigger dogs though certainly caused more damage than yappy dogs though. Hence why I just don't trust any dogs even though I love them
