How can I train my dog to drop a ball on command?

To train your dog to drop a ball on command, start by teaching them the "drop it" cue. Hold a treat in one hand and the ball in the other. When your dog picks up the ball, say "drop it" and show them the treat. When they release the ball, reward them with the treat. Repeat this process until your dog consistently drops the ball when you say the command. Practice regularly to reinforce the behavior.
