Congratulations on your new little one!!
She's probably trying too process this major change in her life. She will adapted I'm sure with time and patience. After all living someone older can be a whole different life for some pets. Then there are older people who seem to stay young forever and their pets may have a more active life. You will truly enjoy this little one once you both really connect. Don't let her fool you. With time and your patience she will turn out to be all you hoped for I'm sure. Because yorkies are full of surprises!! I know you will be thrilled to have opened your heart to her in her time of need. We have 4 all ages from 1yr to 13 and they are truly precious. We are also seniors who happen to stay very active especially with our little troop. Love and treats go along way too. If ours could speak they would all say we never get enough treats for anything!!
have fun and enjoy your new baby!
