I just went through the hunt of finding breeders who leave tails and dewclaws on dogs, we got a silver poodle from a breeder in California, from Genteel Standard Poodles, very natural, everything is left intact on the dog.
Some other breeders are Autumn Shades in Ohio, Silken Poodles in Ontario, Harmony Hunting Poodles in Arizona. Sorry that these are not in the area you are looking for, they are just the ones that I know of. You'll have a better chance of finding natural tails with working, hunting lines overall. I contacted a few breeders in Canada and asked if they would be willing to leave tails on, none were. Some might be willing to if you pay for the dog ahead of time, but then you run the risk of that particular dog maybe not being the best match for you.
As for dew claws getting in the way, being ripped off blah blah, yeah, it can happen, just like with any other toenail. New research is showing that dogs use them a lot more than originally thought, to grip bones, take tight corners when running fast, all sorts of things. They are not the floppy unattached appendages like rear dew claws. A lot more breeders are leaving them on nowadays.
