It’s been almost 20 years since my Toys (wow, how can that be???), but I’ve got a lot of friends in minis right now. Violet was a rescue, but definitely going breeder next time. Genova is my top pick, she has STUNNING silvers and is finishing dogs quickly right now. All around quality and not just conformation focused either.
Clarion is an excellent choice as well, I talked a lot with them before ending up with V. I’ve heard good things about Munaut as well in the Standard circles. Finding a good Toy breeder is so hard Rainbow Toys is definitely not one I’d recommend after my experience
