I have wanted a patio swing for my backyard for a while now, and this year I finally bought one. It is very nice and even folds down into a chaise for reading a favorite book or into a bed for afternoon naps. The dogs think that it is great to have "their" very own furniture in the yard. It is a nice comfortable spot to lay and keep out of the sun.
I guess that in unison yawning means that Maggie and Bosley are bored of having their pictures taken while posing on the swing.
