Give your dog a hand signal - for example, a 'stop' sign with the palm of your hand facing your dog. Instead of giving your dog the treat straightaway, wait a few seconds. Say 'stay' and then give it to them. It's important to reward your dog while they're still lying down, and not if they've got back up.

The foundation of training should be based on positive reinforcement. Positive reinforcement is the process of giving a dog (or person!) a reward to encourage the behavior you want, like getting a paycheck for going to work. The idea is not to bribe with the behavior but to train it using something your dog values.
