One of the most common alternatives to a collar is a harness. Veterinarians routinely recommend that dogs, such as pugs with their short noses, and miniature poodles with their propensity for collapsing trachea wear harnesses. However, it's important to chose the right one. In general I avoid harnesses that hook on the back unless you want to train your dog to pull a cart or a sled. These harnesses actually help train your dog to ignore you and pull you because when you pull on the leash to try to gain some control, they direct the dog's attention away from you.
Dogs come in to the veterinary hospital and to our various handling labs wearing a variety of collars and harnesses. While all of these collars and harnesses are sold online or in stores, some are not necessarily healthy or safe for all dogs. In this article, I provide a summary of the pros and cons of some of the various collars and harnesses for dogs.
