Flying with Chow Chow

I have a 5 year old Chow Chow, and hoping to take her back to Canada from Korea. I'm finding it very difficult to find any airline that allows Chow Chows. Does anyone have experience in this?

Also I'm trying to find ways to take her in-cabin whether that's as a psychiatric service dog or therapy dog.

I've also heard that some people take their dogs to Europe and then stay there for some time and then fly to Canada.
