Hi
I just welcomed a 17 week old Yorkie into our home! She is a beautiful little girl name Piper.. Weighs 2 lbs right now. She is active and full of energy usually.. I noticed that last night and this morning she is sleeping more? She is running around and eating but then she is very sleepy? Could it be a growth spurt? I'm just nervous with her. She had seen the vet yesterday just for a wellness check

and they said she was fine ... Put my mind at ease please!!
