High-quality training collar for dogs made of leather. Recommended especially for young dogs and adults that have trouble learning the rules during walks. The product is a brilliant alternative to chain collars and prong collars. Used by professional trainers worldwide. Designed to prevent the dog from pulling on the leash. When the pet pulls on the leash, the collar gently tightens around its neck, signaling it to stop this behavior. The collar prevents choking, especially for aggressive, hyperactive, or anxious dogs, and allows the trainer to maintain control over the dog. The collar has a rope shape, is very durable, and resistant to mechanical damage. Advantages: - High-quality leather construction - Supports leash walking training - Allows control over the animal - Easy to use - Used by professionals - Features strong, welded metal o-rings for leash attachment - Available in 6 sizes for precise fitting - Lightweight and handy How to choose the right size: When the dog is at rest, the collar should loosely wrap around the neck and not cause pressure. The optimal collar size is one where two fingers can fit between the dog's neck and the collar. To select the correct collar size, measure the circumference of the dog's neck and choose the appropriate size from the list. Note that the training collar does not have an opening and must be large enough to fit over the dog's head.
