joseph312 - Yes, it is possible. I would recommend you start working on this as fast as possible. Firstly, you will need a reliable service that might help you register your dog. I am happy that there are services like https://www.esaregistration.org/esa-letter/. There on the site, you can find all the information you need, and it helps you step by step get an ESA letter, which will help you migrate with your loved one. I have a dog myself; it is a pit bull terrier American. I had the same issue a year ago, and I am happy I have found a solution to my problem. I think it is not a hard process, but it helps very much.
