Interesting. Sounds like the leopard cur registry does a lot like what I think would be a nice change for a lot of dog breeds - to find some way to incorporate a system similar to a lot of the warmblood horse registries. If you want your animal to have full studbook status and to be allowed to produce more registered offspring, they need to pass an inspection of conformation, breed type, health, and performance. Sure, there will be people who advertise their purebreds who don't pass, but as you said, at least buyers who do even a small amount of research would be able to know what they are getting.
Dog Wars is an interesting read about how the AKC managed to pull in border collies despite all the protest about a working breed being included.
So the Tennessee Treeing Brindle is basically a mountain cur? Hm. Perhaps Meg will be ILP-able at some point if I ever decide I want to do that.
Edited because - yeah, no. She looks nothing like one. Right at the bottom of the size range, although within it, and the temperament is pretty on, but looks are not.
