I think there was some bad advice given. The government of Ecuador makes it easy to import a dog or cat, which are the only animals they consider as pets. There is no mention anywhere of an entry tax, only a small fee for the animal's inspection.
The government is not the one with any big charges.
Here are all the steps needed, just three, no mention of any entry tax, only mentioned is the fee for the animal's inspection:
INGRESO AL ECUADOR DE PERROS Y GATOS.
Puntos a cumplir:
1. El Certificado Zoosanitario de Exportación para su perro y/o gato otorgado por el Servicio Veterinario Oficial del país de procedencia en español, detallando el cumpliendo de los requisitos sanitarios exigidos por Ecuador.
Requisitos para perros y gatos procedentes de Europa, Asia, África y Oceanía. DESCARGAR
Requisitos perros y gatos procedentes América. DESCARGAR
Requisitos perros y gatos procedentes de Australia. DESCARGAR
2. Cuando el animal arribará por carga el comprobante de depósito por $26,17 dólares por la inspección de cada animal para la emisión del Permiso Zoosanitario de Importación.
3. Inspección clínica del perro y/o gato, por parte de un técnico de AGROCALIDAD.
That's all! The above steps are from

This short 4:21 YouTube video in Spanish first explains the steps for importing a dog or cat, and the whole explanation takes less than a minute and a half. The rest is for exporting an animal, and also how to fill out an on-line form for import/export (the on-line form is not required, but presented for convenience):

This PDF explains all the steps in a document. The only cost they specify is $24 for the Permiso Zoosanitario de Importación - the import permit issued by Agrocalidad. Another document (as written above in step 2) says the cost is now $26.17.

Here is a PDF that lists all the vaccinations necessary:

If the dog or cat comes with you in the cabin of an airplane (and not as cargo), or if you enter Ecuador by a land point of entry, there is no need to get the Permiso Zoosanitario de Importación - but you must have the country of origin's Certificado Zoosanitario de Exportación, an official document from a veterinarian certifying the animal is fit for exportation and complies with Ecuador's requirements:
"NOTAS:
Cuando el perro o gato arribe al país en la cabina del avión junto al pasajero o por un paso fronterizo terrestre, no necesitará obtener el permiso zoosanitario de importación, pero obligatoriamente deberá presentar el Certificado Zoosanitario de Exportación."
The above is from

So what are the costs? The governmental costs are minimal - under $30. The only costs are what an airline wants to charge. If it were me, I'd consider buying the dog a ticket and having it in the cabin with me, that way you don't need a Permiso Zoosanitario de Importación form. But even that is less than $30.
I would also get in touch with the nearest Ecuadorian consulate or the embassy in the United States to see if they can clarify things - but don't be too surprised if they can't:
