Serious answer is if they are lying about the meat they sold, likely did not put them out in a humane manner. They probsbly had atrocious conditions while holding the dogs for slaughter too. I'd say the same can apply to cows, but this is Mexico and I am not even that familiar with our own laws here let alone another country. The dogs might have belonged to other people. Probably also trying to stack charges on top of lying about dog meat.
