According to senior dog trainer Clarke Young Jr., the dogs are trained to recognise C4 explosives and TNT, using a rubber ball to play a game as the dogs associate the explosive smell with the ball.
Prema rečima višeg instruktora pasa Klarka Janga juniora, psi se obučavaju da prepoznaju C4 eksploziv i TNT, korišćenjem gumene loptice za igru, za vreme koje psi asociraju miris eksploziva sa loptom.
