Harnesses are a safe, easy-to-use solution that not only prevent tracheal injuries from sudden lunging, they also eliminate the possibility of your dog slipping out of a collar. Our rugged nylon reflective dog harness features reflective tape for excellent nighttime visibility, plus your dog's name and your phone number are embroidered on the harness, should your dog stray a bit too far from home. Measurement reflects girth. Please measure your dog right behind the front legs, around the thickest part of the chest. Personalise S/M with 26 characters, M/L with 30 characters. Made in USA.
