Peekaboo, also known as 'middle' to some owners, has your dog walk around behind you, sit, and poke their head through your legs. It's a simple, endearing trick and a useful foundation for teaching more advanced tricks. Beyond looking impressive, peekaboo gives your dog a specific place to park out of the way while you're briefly occupied. Teaching the trick involves luring your dog with treats to position them between your legs, rewarding the behavior, and gradually introducing verbal cues. If your dog struggles, widening your stance and lowering the lure can help. This trick works well as a family activity and makes a nice break during training sessions.
