My dog has been trained to always come back to me the instant I call or whistle. It’s taken a lot of work to get this response. And now he consistently listens for me and responds immediately—no matter what distraction is vying for his attention. Since I can trust him, I’m able to take him off his leash and let him run around and explore the fields and woodlands. In short, because he’s been properly trained and can be trusted even when facing temptation, he can enjoy his freedom.
