this lady brought her dog to Ecuador from Canada and states:
"As far as getting an animal into Ecuador goes it’s a fairly straight forward process — as long as you follow all of the Ecuadorian guidelines. I phoned the Ecuadorian embassy in one city and the Ecuadorian consulate in another just to cross check information"
"Any problems we did encounter were with the airline(s) themselves, so my advice to anyone considering bringing their pet is to make sure you double or even triple check any information they give you."

"Importing pets such as dogs, cats, and birds in permitted, however you will need to coordinate with the Local Ecuadorian Consulate prior to arrival to obtain the necessary documentation.
For a $50 fee, they will provide you with a 'Animal Health Certificate', but they have some requirements of their own. "
more info at the links of course.
I don't know how up to date that info is but at least it gives you the names of some places to contact (Ecuadorian consulate, USDA)
good luck!
