i remember pakkun longing for someone to touch his pawn. it was during the chunin exams when shikamaru, naruto, sakura and pakkun went after sasuke (who was chasing gaara). he asked shikamaru and sakura to give him a five, which neither did!
Is Pakkun and Akamaru the only dogs you guys know about? Well Bull is the best and I forgot the other dog name. I'll post it later when I search his name.
