Sandra, This is probably coming a little late as you sound like you were on your way to Canada when you posted but just for future info. We have our 4 shih tzu on the truck with us and we carry all their health records much like we would our own. After many trips into and out of Canada, we've never been asked for any documentation pertaining to our dogs. Now it should be noted that any time the truck stops they are "excited" thinking it's time to go out and play so they're not quiet at all, just so you know there's no chance that they could have "snuck" through. Hope this helps. DD
Of all the things I've lost in my life, I think I miss my mind the most!!
