When you travel from the USA to Canada with dogs, it can be a seamless process with the correct paperwork. For humans, this means having a valid U.S. passport and for dogs older than 8 months old you must have an official rabies vaccination certificate from a licensed veterinarian which states that the dog is rabies-free. Additional regulations apply to dogs entering Canada by plane. All used images licensed under Creative Commons. Sources: ****** ****** ****** * ****** ******
