Top of the line collars, DOGTEK's waterproof constructed receiving collars produce a clear and recognizable tone that has been tested and proven effective in reinforcing the electric stimulus. The EF-4000 collar automatically increases the tone's pulsating rate in the warning zone as your dog approaches the correction zone. This will expedite the training process so that your dog will learn EXACTLY where the invisible boundaries are, where ever you decide to set them.
The safety and well being of your pet is a top priority to us. You may rest assured; all DOGTEK products are tested and approved by veterinarian and dog training professionals. Our mission at DOGTEK is to offer our customers the most technologically advanced, durable, safe and reliable dog training products in the United States backed by superior customer service and support.
