Di Limbazi is the only breeder of european dobermanns I am aware of in Alberta, that also health tests. I cannot speak as to their temperament.
I also doubt that they will go all-natural.
I lucked out with a service dog from a local breeder and as it later turned out her damside traced back to lines that produced multiple therapy-certified dogs. Heartwood Dobermans who are on the US west coast are expecting a litter. Not european, and they are american so chances are the dogs will leave cropped and docked. They have also produced at least one SAR certified dogs. Who is the brother of my girl's granddam.
There is also Vom Koby Haus - these are european dobermans but several are certified therapy dogs. However they come from strong working lines so it can be a lot to handle. One Therapy certified stud was bred in May to a european import bitch with a BH who is not in the "hard, intense" working drive category but more from show lines who work. A bit like the Heartwood dogs. X-rays were done yesterday, she's expecting minimum 8 possibly 9 puppies though given how smushed the puppies are I counted up to 10 and some people saw 11.
She is located in Quebec however. She is flexible about ears but not about tails. Litters | Dobermanns Schwarzer Stolz
But actually... speaking from experience as a doberman SD handler, I do believe there is a benefit to them being cropped and docked, especially for psychiatric work. I debated on this before I got mine - should I go with cropped ears or natural ears? (always preferred docked tails though). I thought that the softer looking drop-ears would be more acceptable to the public visually. But guess what? After 4 years of owning and handling her and being in the SD community I realised two things:
1 - you'd think the general public knows how to read patches on harnesses, or has basic education about SDs and how to interact with them (don't look at them, don't touch them, don't try to distract them) but they don't. People are rude and disrespectful and will tamper with what is essentially a very expensive, vital and sentient piece of medical equipement and shamelessly so, just because it's a cute doggy. Some people will even get entitled and throw a tantrum if you intervene and tell them not to.
2 - No one ever messes with my SD because she is a doberman with cropped ears. As someone with PTSD and anxiety as well as low tolerance for the pressure experienced from people crowding me and being in my bubble, I need space. In fact even when she off duty and not wearing her harness, I've never had anyone attempt to touch her without permission, or had a parent let their kid approach/touch her without permission. I feel really bad for the handler-SD teams who are constantly harassed and distracted by inexperienced people but I've only had one person ever try to touch her on duty, and that was a little girl who didn't know any better (and seemed to understand when I explained).
3 - people give me SPACE when I am with my cropped and dock doberman on duty. I occasionally will have people come up and ask if they can touch her but they are always tremendously respectful about it, and they enter our space with respect. Nor do they kick up a fuss when I tell them no.
Just something to seriously consider for your friend regarding the owning and handling of an SD. If she is worried about the laws, it's not illegal to own a C/D dog in Alberta. It's just that the AVMB voted that vets can no longer crop, dock or remove dewclaws, and any vet caught doing so can lose their license. But there's no legal ramifications to that.
