Stop buying cheap inferior dog collars and start buying products that are made to last. Our Alpha-quality dog collars are handmade using locally sourced genuine leather and heavy duty nickel plated solid brass swivels, D-rings and Chicago screws. Collars are designed to fit pups across the pup-spectrum (see above for sizes before ordering). If your pup's measurements are on the lower end of the chosen size then opt for the smaller size as the collars will stretch a little after use. While our collars are made from superior materials, they are not for heavy pulling dogs. So if your dog is a heavy puller, it is recommended to use a choker or a harness not our leather collars as they will stretch.
