I checked out their site too... they sound like a Broker to me, or a puppy mill operating under the guise of a broker
. Anytime they list several different breeds a red flag should go up. Also, the fact that they are listing teacups - which don't exist! - is a red flag to me. The site is too flashy and.. I don't know.. just gives me a bad vibe... doesn't say to me "caring, responsible breeder" - know what I mean?
I would keep looking - Try finding a breeder local to you where you can actually go to their home and see the living conditions the puppy are raised in and see the sire and dam. There are LOTS of members on here living in and around NYC - ask around and see if anyone recommends a breeder.
Good luck in your search! And welcome to YT!
