He's not at all sure how he got his name, but is willing to figure that being a shepherd mix pup warrants reference to intelligence and therefore is willing embrace being Brain with all of his gusto. At about 18 lbs now, Brain is ready to grow into his big boy pants over time. He is a small guy in a big world but is settling in just fine. He does great with his puppy friends but is ready to mosey on into your heart and life. He could easily join an existing pack but would be just fine as the center of your world. He is primed and ready to be an A student....his name IS Brain. For smart and sweet, think with your heart and adopt this guy. He'll take over the Brain job.
