This might sound crazy, but in some countries, certain breeds are banned. If your pooch is a banned breed, he will not be allowed to enter, under any circumstances. If that’s the case, your pup will likely be sent back home (at your expense). Depending on the location, there’s even a chance that he could be euthanized.
While every country is different, the breeds that are most commonly banned include Staffordshire Terriers, Pit Bulls, Neapolitan Mastiffs, and Rottweilers. It’s far better to check ahead than to bring your dog along and find out that he isn’t allowed.
