Hello, Colby's dad here, What I like to do with Colby is take him for a walk at about 8 P.M. for about a half hour. This gets the last of his energy out so he can have a good nights sleep. Most of the times he will fall asleep on the couch at 9:30 and sleeps the whole night.Perhaps running around the house before bed time may just get your Yorkie all fired up and wants to keep playing. Good Luck Mamaboy
