<human>:  How do you teach a dog to come when called?
<bot>: The best way to teach a dog to come when called is with positive reinforcement. Start by teaching your dog a word or phrase like "come" or "here". Then, every time your dog comes when you call, give them a treat or some verbal praise. Additionally, you can use a leash and start practicing recall in your house or an enclosed area, gradually moving to larger and larger open spaces, so the dog is comfortable responding to your call from a distance. Finally, practice, practice, practice and be consistent in your approach to ensure your dog learns this important skill.
