As far as collar v. halter, I feel the halter is better because my little girl, Misty, gets coughing fits when I put a collar on her. The vet told me the collar digs into her trachea and causes her to cough. Kanga chose my most favorite color. Misty is black so we chose a red halter. By the way, Kanga is so adorable.
