(that site maybe not totally accurate)
A bit bigger than a mini, a bit smaller than most Standards. There are some really nice Klein Poodles in the US.
This is a breeder, whose site just happened to come up when I did a search for Klein Poodles. (so, I know nothing about them personally, just using the site for the info). Accurate info on the variety, and they do appear from the website to be a decent breeder.
