Happy new year furfriends and furparents!
I went home to my Province to spend the holidays with my family, so my baby boogie stayed at my boyfriend's house. My boyfriend has 2 shih tzus so my baby had a playmate for 2 weeks. We noticed that he ate extremely a lot and gained weight when he was at my boyfriend's house. Seems like he loves having playmates.

Now he is back again at my house and he seems super sad. He doesn't do his usual routines of waking me in the morning by licking my face. And also, he doesn't want to eat!

Seems like he became distant towards me as well
What can I do about this. Can we work it out or do I need to get a brother/sister for him?
Also, please share what type of breed have you mixed with your yorkie and how was the experience?
Thanks a lot guys!
