So why do I avoid the appealing cobra buckle dog collar? Besides the fact that my philosophy of training is to focus on rewarding the dog's good behaviors and removing rewards for unwanted ones until the dog forms good habits, there are many medical and safety reasons too. Not surprisingly, strong yanking on the neck with a chain can cause health issues. If the force from a dog pulling on a flat collar raises intraocular pressure, imagine how high that pressure must rise when you actually yank the dog with a thin chain! Even if your dog has no eye issues, the appealing cobra buckle dog collar, is notorious at exacerbating airway issues. For instance it can worsen coughing in dogs prone to collapsing trachea (weak trachea that flatten more than they should) and affect the ability of dogs with small tracheas, such as Pugs and Bulldogs, to breath. Additionally, dogs may develop neurological damage when the corrections are strong enough. The damage, called Horner’s Syndrome, can result in changes to the pupil in the eye and nerve-induced lameness in the front leg. Lastly, even if you don't use a appealing cobra buckle dog collar in the manner described above, appealing cobra buckle dog collars should never be left on an unsupervised pet. They can get caught on something and tighten to the point where they strangle the panicked dog.
Once the dog loves putting his nose into the head halter and the owner puts it on, the owner may need to engage the dog in fun behaviors to distract him from the funny object on his face until the dog gets used to it.
