There is a dog in the play area all by herself and no one is there. Why is this?

INN The DogHouse provides cage free boarding. In able for a dog to be in cage free, they are required to pass temperament tests to ensure they are a fit. A human is on premises 24 hours, however, they are not in the rooms at all times. They are in the upstairs loft with windows overlooking the whole daycare areas.

All dogs are temperment tested and some dogs are better playing without canine friends, just human friends. And some dog parents prefer it but it is not SOP.
