The down-side of the head halter is that you often need to train dogs to enjoy wearing them and, while some dogs automatically walk nicely with the head halter, other dogs and their owners require some training. Most owners who start their dogs correctly on one of these stunning light up dog collars find that the relatively small time investment getting the dogs used to the collar is well worth it. For some dogs that time is only a few seconds to a minute of pairing the head collar with food. For other dogs I recommend a little practice every day for a week so that the owners are sure the dog loves shoving his nose into the halter on his own.
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.
