Drug sniffing dogs at Mexican Immigration? are you kidding me?
The airport security in Mexico is a joke, they have a thing set up that looks like a stoplight, as you pass thru it will go green or red (totally at random) if it's red you get your bag inspected, if it's green you go thru unchecked.. I've flown into mexico dozens of times, and 4 times since 9/11 and never been checked.
I'd be more concerned carrying it into the airport on the US end.
