I could, but am not going to, show you the dog bite on my Wife's bum.
No, she wasn't trying to reach out, hug or kiss the dog with her bum. Just sitting talking with a friend and it ran up and tried to take a hunk out. Years ago and not as bad as pictured. They are just faded scars now.
More often than not, it is 'not' a shared responsibility like this one.
IMO, Thailand is in need of a more robust Animal 'Control' system. Not an Animal 'Protection' Act.
Mandatory tagging/vaccination would be a good place to start.
