Dale Valentine is the toddler brother of Skeeter Valentine.
Dale Valentine is a well-mannered kid and gets along well with everybody, although he accidentally offends Doug when he calls him "Big Nose" in the episode, Doug's Big Nose. Dale's biggest role in the entire series was in Doug Loses Dale, where Doug babysits Dale and accidentally loses him right before Skeeter's parents come home. Even though he is still a toddler, Dale occasionally demonstrates signs of substantial intelligence, such as when he is the only person who recognizes Doug underneath the Hamburger Boy outfit in the episode Doug is Hamburger Boy.
He is voiced by Fred Newman.
