Speak to Peter Spoons. The locals ate his dog that he got 'shipped' over from Ozzy after it got hit by a truck.
Another 'old wives tale' that I was told, is that other dogs always know if a person has eaten dog-meat and keep away from you!!
Many years ago, I was given a bottle of that by my Manager for a Christmas present (Brixton Branch). It came in a velvet bag and I didn't realise the cost if said item (at the time!!!).
