I would also be interested, if this is a factor of CHOICE, what choice a person who wants to buy a puppy from a reputable breeder who docks at 3 days old does if they want an UN docked dog?
Seems that choice is taken away from those people?
I'm not really a Pem person, but typically, if you want an undocked Pem puppy, you have three options.
First is to choose a Cardi instead. The breeds have very different personalities, but similar exercise and care needs- a lot of people like both, and people who haven't fallen exclusively in love with one or the other switch back and forth pretty easily.
Second is to get on the waiting lists with rescue. A significant portion of people who are very serious about the cruelty of docking prefer rescues to breeders, anyway. But rescue gets undocked dogs with some regularity.
Thirdly is to import a dog. Expensive, sure, but not at all undoable, especially since there are a number of Finnish and Swedish breeders who send dogs to the US fairly regularly.
Lastly is to follow the chain of referrals.
There ARE a few reputable breeders who have left pups undocked, but in almost every case, it's been unusual- either they were planning to export a dog and would make their best guess as to show quality pups who would be the one (it's extremely unusual to export pets.) or they had a dog with a DQ fault (in this case, body white - 'whitelies') that would obviously be PQ no matter what. And then you wait.
