Cooper is an active and spry senior dog.  His coloring and build suggest an Australian Shepherd and Black Lab mix, with the unique blue eye/brown eye combination.  He is very attentive and curious, and enjoys being near his owner.  He is quick to learn new routines and sleeps well through the night.  While his hips give him occasional trouble, he is happy to run with the other dogs in our pack in the yard and gets up and down stairs fine.  He would do well as a solo dog or with another dog in the house, once acclimated.
