When Florida resident Bill Kelly gave one of 3 scratch-off tickets to his family pet, little did he realise what the outcome would be.

Bill picked up three $600 Million Gold Rush scratch-off tickets at the Publix and put one in his dog's Christmas stocking.

Turns out his dog's ticket won a $3 million prize, and Bill was over the moon.
