Merle poodles and schnauzers aren't purebred. I don't actually have a quibble with thoughtful outcrossing, but if someone tries to register merle dogs, they're lying about something in the dog's lineage. It's simply not possible for a merle dog to arise from a poodle/poodle or a schnauzer/schnauzer breeding. And introducing the merle to the poodle gene pool brought along a bunch of health risks purebred poodles don't have (probably the same with schnauzers...I'm just more familiar with it in poodles because I researched before getting my hairball). It's the worst kind of "designer dog" BS...making dogs LESS healthy just to get trendy-looking pups to sell for more money.
