She looks alot like my New Zealand X Rex cross
The body type of a New Zealand with the coloring of a Rex,very pretty
You can tell she has rex in her, but she's not pure.
So my best guess is, you have a New Zeanland X Rex cross as well
New Zealand Cross ... not rex. Coat is too long and course for that. Rex has a plush soft coat even when they crossed to NZ it produces patches of velvet coat in the colors. The Rhinlander carries a similar color pattern also ... and has more of the NZ style coat. When crossed with other breeds, the spots blotch out.
My first thought was a rex mix. Certainly seems to have the body shape for it. Enough generations away from the pure rex relative, and it probably would not have that typical rex hair, but would still retain the body shape. How big is she? I love the spot around her eye!
