Like someone already said, charts are just guessing especially when you don't have a history of your dog's ancestors and what they produced.
A reputable breeder will have an established line of dogs and will know the background of those dogs and what came out of them. Then they can make up their chart according to the facts they have to go on concerning past history but still it is an educated guess.
It sounds like you have not met the breeder or the parents of your pup. That is a red flag. I would venture to guess that there are reputable breeders in your area or at least in your area of the state.
Here is a link to search for AKC conformation clubs in NYS:
American Kennel Club - Club Search and Directory
There are quite a few. Most of those clubs will have a breeder referral person that can point you in the right direction as far as what they consider reputable breeders. They attend shows all over NYS and in other states so they know a lot of breeders.
Some will also tell you to contact the YTCA but any YTCA member is also going to belong to their local AKC club as well. It is a good idea to to to the YtCA website. They are rebuilding it right now but when it is complete it will be a great source of information for you. You can find breeders there now though.
These people do sell pet quality pups. Some have some beautiful little dogs. The thing you have to do is talk to a lot of them and get a feel for what you are hearing. Learn what questions to ask and how to decide if you got the right answer. You have a right as a pet owner to get the kind of dog you want. People who do not bother to learn the history of their breeding stock cannot promise you anything about the pup you buy. They have such a huge gene pool that you just have no way of knowing what is back there and what will pop up in your pup.
There are also "sticky" areas here on YT that are informative and will help you to avoid possible problems....and there are many out there right now.
