If you decide to use a head halter, be sure to acclimate your puppy for 2 weeks before adding the leash. Lure your puppy’s nose through the nose band and rest the halter gently on the bridge of her nose. Repeat a few times every day for a week. During week 2, put the head halter on your puppy, clip the back and feed her a meal. Take off the halter. After a few days of that, attach the head halter and then go for a walk. Toss treats on the ground in front of you if your dog tries to fuss with the head halter.
