Hi. Welcome to YT and congratulations on your new one!
There are very experienced breeders who can probably give you much more detailed advice than myself. From just a pet owners view: My first yorkie I got at 8 weeks of age. It is my experience that little ones this age are so people dependent. That is a long day for a little one to stay by itself. That is probably why she is regressing a bit but did better when your mother could stop by twice a day and give her some mothering. Is there any way your mother can continue on that schedule for the pup until she is a bit older and a little more independent? She has just left her mom and fellow littermates not so long ago. I'm sure she's having anxiety being left there that long by herself. |
