Don’t use choke or prong collars if your dog is pulling on the leash. They are forbidden already in many countries. Use non aversive techniques and try the dog leash for dogs that pull from traindee for sustainable training results! Stress-free training without causing pain or scare the dog. That’s modern and positive dog training! Take your time and think about what choke and prong collars are really designed for. The principle is to punish the dog for pulling by inflicting discomfort and pain. Also serious physical and emotional damage may occur as it has been associated with whiplash, fainting, spinal cord injuries leading to paralysis, crushing of the trachea with partial or complete asphyxiation, crushing and/or fracture of the bones in the larynx, dislocated neck bones, bruising of the esophagus, bruising and damage to the skin and tissues in the neck, brain damage and prolapsed eyes caused by sharp increases in pressure in the head, and other injuries. When the dog pulling on leash, the metal spikes of prong collars pinch the skin around the neck of the dog and can scratch or puncture them which can lead to scar tissue and the dog building up a tolerance to the painful pinching sensation and thus continue to pull, making walks even more difficult. Dogs can become aggressive or fearful, both not good options, because they interpret the tightening of a choke or prong collar around their neck as a stranglehold. With the right, non-aversive dog training equipment, patience and positive reinforcement, walks can be a pleasant experience again for both human and dog. Find a good dog trainer to help you with the various techniques to handle leash pulling with modern training methods as this will help you and your dog to stay healthy and stress free.
