If you want to work with her it's your choice. I wouldn't by the tone of emails and questions regarding breeding and costs.
I smell a possible scam or a possible inability to pay for a puppy and related costs.
There are many families looking for puppies in the NY/NJ/Conn area for better weather in the spring. If you need referrals in those areas after the beginning of April, feel free to email me and I will try to help out.
