When teaching a puppy to sit, I like to build a little duration from the start so the behaviour becomes more meaningful. Using a piece of food, gently lure your puppy into a sit, then mark the moment they sit with “yes” (or a click) and deliver the reward while they remain in position. Follow this with a couple of additional treats, given one at a time, to help your puppy stay in the sit calmly. Once you’re ready to finish, use a clear release cue such as “okay” (or “free”/“break”) and give a reset treat to encourage your puppy to move out of position. This helps your puppy understand both how to stay in the sit and when the exercise has ended.
