Affiliate disclosure.

Companion Letter participates in an affiliate relationship with ESA Pet. If you follow a provider link and make a qualifying purchase, we may receive a commission.

Which links are commercial?

Buttons such as “Explore ESA Pet,” “View ESA Pet,” and “View ESA Pet options” are affiliate links. They use a tracking destination before taking you to the provider. ESA Pet is the only commercial evaluation provider promoted on this site.

What the relationship does not mean

We are not ESA Pet, a healthcare practice, a government agency, or an animal registry. We do not provide evaluations, issue documentation, promise medical approval, or decide housing requests.

Our ESA Pet page describes a published service process. It is not a first-hand treatment review or a comparative ranking based on testing multiple providers. Images and examples are illustrative.

Your decision and the provider’s terms

Review current pricing, appointment details, professional licensing, privacy information, and refund terms directly before purchasing. Provider terms govern its services. The information on this site does not modify those terms or guarantee a particular result.
