I have a mate who knows Lorraine and Aaron Cohen - they tell a story of some cocaine they had that they buried in the sand on the beach they live on. Their dog saw them bury the bags. They went out - when they came home they found white powder all over the lawn and the dog looing like he was off his face. Aaron raced inside and got a couple of record album covers and attempted to scrape it up, and recover what he could.
We had a goat in OZ that would munch a cannabis plant if he got near it - they love it
