On the transfer side, check the Avianca website for the travel requirements, which are independent of the requirements for leaving the country and entering the destination country. Basically it is a certification of the animal health agency in the country of origin and procedures in the country of destination
I think it is best to talk to the avianca agents but I, who love dogs, first thing I do is buy a first class ticket in case I can take it with me and so people do not bother
If the dog weighs less than 17 lbs, it can go in the cabin for $ 130 if it weighs between 18-100 lbs, it can travel as luggage for $ 200 plus taxes. It is best to check with Avianca directly at 1-800-284-2622
Ask the airline. They are simple procedures
