Country Brook Petz Martingale Heavy-Duty Nylon Dog Collars are a great solution for your pup’s pulling. Made with two loops, our martingale style collar will give you gentle control when walking your pet. Perfect for training, our collar is designed to prevent your pup from slipping their head out of it. As your pet pulls, the collar will tighten without choking them. When the tension gives, so will the collar; the martingale will loosen when your dog stops struggling against it. The limited closure of the Martingale collar prevents it from becoming too tight. A no-slip, adjustable-choke collar is an excellent solution for hard-headed pups who slip out of their collars. Our collars create a secure experience for your dog.Once you receive your collar, open the collar wide by adjusting the metal slide. Slip it over your dog's neck and decrease size until you can comfortably slip only a couple of fingers under the collar. The unique limited closure prevents the choke from becoming too tight.Constructed using 100% nylon webbing, our collars are ribbed, soft, and sleek to the touch; they also sport a bit of sheen. We at Country Brook Petz pride ourselves on only using the best hardware and you can rest assured that these collars will withstand whatever your pup brings its way. All of our collars are handcrafted after the sale. We want doggos to be able to show the world their new collar immediately, so be sure to measure for the right size. You can check this out by using a string or tape measure to see where the collar will fit snugly and comfortably on your dog’s neck.Country Brook Design cannot be held responsible for misuse of this product.
