Most adult dogs don't really need a nap. They will nap if worn out from a lot of exercise but generally they don't need it. Usually they just want to be with their people but if they are bored they will nap.
Gracie is like a lap magnet. If someone sits down in the living room she makes herself comfortable on their lap right away.
Just like most humans they are looking for something to do even if it means watching you cook in the kitchen. Gracie will walk along with me as I vacuum. I think she is making sure I do it right!
But when is is bedtime she is always ready to cuddle up and go to sleep.
