Thinking about Cavalier Adoption

I’ve been thinking for a few years about getting a cavalier and I think I’m at the point in my life where I can properly take care of a dog. I’m curious as to what people in this thread have experienced in the adoption process?

I’m conflicted because I’ve always adopted dogs from the shelter my entire life, but from what I’ve read online, I think the temperament of Cavaliers would fit really well with my lifestyle. I am considering getting them ESA certified as I experience a lot of anxiety/c-ptsd and my therapist recommended it. I know cavaliers can be great service animals but I would not train as in depth to need that kind of certification.

Would be interested in your thoughts, and thanks for your time!
