When Chipper was a young puppy he developed double pneumonia. My mom nursed him back to health, but he always seemed mentally slow, probably because his body fought off the sickness instead of developing. He needs his little sister, Buffy, to tell him what to do. Although Cocker Spaniels are not known to be smart dogs, Chipper seems especially dumb, even for a Cocker. But he makes me laugh – a lot!
