The collar touch exercise is designed to help your puppy remain calm and comfortable when you handle their collar. Start by pairing food with touching the collar: initially, offer a treat just before you take hold of the collar so your puppy begins to associate the approach with something positive. Next, progress to giving the food at the same time as you take hold of the collar, and then move to feeding immediately after you are holding it. Only move to the next stage when your puppy is relaxed, not moving away, and not mouthing or fussing when you reach for the collar. Over time, gradually phase out the food while continuing to handle the collar calmly and gently, ensuring your puppy maintains a positive association with collar handling and sees it as a safe, stress-free experience.
