I don't claim to be a psychiatrist or anything but methinks deep down inside, subconsciously it might be possible that you really might not want a poodle. Maybe in the back of your mind, it all seems too over whelming. (?) I could be dead wrong of course. And I wouldn't blame you one bit for being cautious. However, your expectations of a breeder, to me are bordering the unreasonable. You shoot down peoples' suggestions who are trying to help or give some reason they won't work or what's wrong with the suggestion...defaulting to the negative it seems. You don't say what state you live in (unless I missed it) so no one can suggest a breeder. I can come up with loads of very fine breeders in my state of Washington. I could get a poodle in a heart beat if I wanted one. I like Farthing/Sovereign poodles in Eatonville Wa. I like Lakeridge in Renton. Those people would have leads to more puppies. Sovereign (same as Farthing) has a white 6 month old male poodle available now.https://www.farthingpoodles.com/nursery/
Does she do few vaccinations? I doubt it. Does she feed raw? I don't know but I kind of doubt it. Does she want to meet prospective buyers? Yes. I would have no problem with that. You should, if at all possible...if the breeder is in your state go meet them, look over their facility, check them out as well as they should be asking you some questions too. I find it difficult to believe that Washington state is the only state that has some stellar breeders with puppies on their way or already available.
So, you have to get on a waiting list perhaps? That's the name of the game. I went on a couple, one after the other when looking for my Doberman. And it took me a while to find a good breeder in my area for my toy poodles. But once I found my breeder, I got not one, but TWO poodles. Other well bred purebred dogs I've gotten in the past...no problems hooking up. So if I didn't have much trouble and most of the people on this forum, for instance didn't have too much trouble or an inordinate amount of waiting, what do you suppose is the reason you are the rarity here? How long have you been looking? Maybe it would behoove you to take a step back and try to look at this from an especially objective view. Just finding fault with the breeders isn't going to get you anywhere. They're not going to care what you think. Let's face it. There has to be some logical reason why this isn't working that you get a poodle. It is not that there aren't enough good breeders. I don't think they're all unreasonable people who won't work with buyers or no one here would have a poodle either. And they'd all be poodle hoarders being arrested because they didn't sell a single puppy.
Another thing you might consider is thanking people here who are bending over backwards to try to help you. This way their helpful behavior won't extinguish from lack of a positive response. You give no information as to the state you live in...don't want to answer that question. (unless I missed it, which is entirely possible) So no one can point you to a breeder near you or help you research the breeder. Maybe I missed that.
The only thing you seem to not be overly particular about is color. That's a good thing. Maybe it would help to loosen some of your other criteria. Forget what they're eating. If they're a good breeder, no doubt their dogs are thriving and surviving just fine. Following a typical vaccination protocol when you want less? So do less later. For now...deal with it. I did. Most people here did. My breeder was good but feeding a food I thought looked like sh!!. I changed their food when I brought them home. They're just fine at almost 6 years old. Oh and you better believe it that I went to look this place over and met the breeder. Multiple times. And then picked them up. Naturally breeders want to know how their puppies will be taken care of and who is buying them. I know some don't scrutinize that carefully or sometimes they ship them. But if possible, I think it's really nifty to go see them. Naturally they'll be receptive to questions put to them as well as long as you're polite and don't come off as too demanding or entitled. If not, then they're not good breeders. Most breeders I talked to prior to getting my puppies were glad to answer my questions which
were limited to genetic health testing, longevity of their ancestors, what they did
die of, what type and amount of socialization they have received up to now...brief description. Any grooming practice? I did not ask that they limit their vaccinations or that they feed a certain food. That might be insulting and it's just not necessary. OR plausible. Most breeders will vaccinate their puppies because things like parvo are incredibly deadly. You can limit that later on if you so choose. So if you really want a puppy or adult dog, you really should be able to find one. But you might have to bend a little. Good luck.
