Hello, I'm preparing for a lot of rv-ing after I retire in January, maybe even full timing. In addition to traveling through the western US, I'd like to be able to travel into Mexico and Canada, but I have a dog and 2 finches. I've tried to find info online about what is needed to pass over the border with pets, but didn't find anything that really spelled it out for me. I'd really love to hear from anyone who has personal experience in this instance, and any recommendations/preparations I should take into account. Thank you very much.
