One of the most important, and most underused, foundations of training is attention. Before your dog can learn anything from you, they need to be tuned in to you. Eye contact is the gateway to that connection.
Teaching your dog to look at you on cue, really look, focused and present, creates a communication channel that makes every other skill easier to teach. A dog who checks in with you regularly, who turns to you in new or distracting environments, is a dog who is engaged and ready to learn. Practice asking for eye contact before every command and before every reward. Over time, you'll build a dog who is genuinely paying attention to you rather than simply reacting to the environment around them.
Start in a calm, low-distraction environment. Hold a treat near your face, and the moment your dog's eyes meet yours, reward them. Gradually build duration, asking them to hold eye contact for longer before the reward comes. Then practice in more distracting environments. This one skill will transform your training.
