yes. balls.

just a quote from a book I'm reading-
“Last night Edgar, an adolescent wirehaired Dachshund, came over to visit. In twenty seconds his nose located the errant tennis ball under the couch. He began digging and whining, desperate to extract the fuzzy golden globe. We showed him bones, chew toy, rope toys, interactive rubber toys, and heaven knows what else. He wanted the ball. Later that night I turned on the local television news. As much time was devoted to the fate of golf balls, baseballs, and basketballs as to world peace, world hunger, and medical epidemics. No wonder we love dogs so much. No one else understands our obsession with balls so well.”
