There is very little money allocated to animal control in Mexico, which means that a lot of disease carrying stray animals roam freely throughout towns and villages. Try to keep your dog on its leash and away from strays at all times. If your pet comes into contact with (e.g. gets bitten by) a stray, gets a tick, or even eats tainted food which is often purposefully left
outside to poison the strays, it can be difficult to find a well-trained veterinarian in some areas outside the cities.
Be sure to visit your vet and ask for travel recommendations and that their vaccinations are up to date before traveling to Mexico. Speaking of strays, though ~ don't forget to make sure that your pet's ID tags are current, so that he/she isn't mistaken for a stray!
