Every night, right before bed, I take the puppy outside for one last time. We usually end up playing fetch with one of his favorite toys, the tennis ball. Tonight around 10:30, while playing, I realized just how keen his nose is becoming. He did not once lose that ball, even though I was tossing it into the shadows of the front yard. Once, I thought he had lost it, but after almost five solid minutes of nose to the ground searching, he came back with it in his mouth, tail wagging. I think he would make one heck of a narcotics dog, or search and rescue.
