It turns out that 44 states do not prohibit eating dog meat (although I believe that California is one of the 6 that restricts it). Still, that's plenty to work with. My idea is to set up food stands at street fairs, art fairs, county fairs, and other typical summer weekend events. I'd name them The Real American Hot Dog. The prices would be really low: $1 for a hot dog or burger, $2 for a stew $3 for a kabob, $4 for a steak. Maybe we could even get the local animal shelter to bring some live specimens too, with a slogan "Adopt them today, or eat them tomorrow!"
I'll classify the whole thing as art and apply for an NEA grant.
Unfortunately, the only thing that will happen is those states will outlaw dog meat, just like the other 6. It won't get anyone thinking about why it's ok to eat a pig or a cow or a chicken but not a dog.
