I feel your pain. A year and a half ago we got our 1st Yorkie puppy. We absolutely adored her and she was lavished with attention from us and extended family, well seems she likes us ok but appears to be more dog oriented.
She will come and sit by me in the evening in my chair but it is not uncommon for her to get down if I pet her. Seems sometimes she is a touch me not. She is happy to see us when we come home from being out but not like other dogs we have had. We got another Yorkie who was a year old and she is more attached to us. We call her a velcro pup. Hope it is just a temporary thing with your pup. I think part of our girls problem is she is very insecure by nature but we still adore her. I guess true love is when you give more than you get.
