Oooooh this is getting a little heated... i havnt even looked at the link to comment - but think i may have to now!
my personal opinion is and this is purely from the dogs point of view & welfare is that all dogs MUST be insured, then if the person cant afford the vet bills then the dog wouldnt suffer.
mmmmmmm, not sure. I guess, initially, go see a solicitor and seek professional legal advise, and then pursue it as a private thing.
dont know if you are aware Sam, but if that person has home insurance where you assessed & subsequantly were attacked by the dog, then you will be able to make a claim against them as the liability part of the home insurance will cover usually up to a million

because it happened on the property and the owner will be liable - with whom the liability will cover - does that make sense how i wrote that????
