One time several years ago we were camping at Adam Lake Campground in Turtle Mountain Provincial Park in Manitoba, and decided to go see the International Peace Garden. We left Canada, but didn't actually enter the US. Our dearly departed husky was with us, and just stayed the afternoon there. As we came back, we had to go through Canada Customs -- fortunately, we had our passports and dog papers with us, just in case. They checked our credentials and didn't even look in the back seat of the truck, and we didn't volunteer any information. But if they did asked us about him, we had everything necessary.
