Our leather dog collars are handcrafted from the finest materials. We use 100% full grain genuine leather and non-corrosive alloy for hardware that ensures these dog collars will last for a lifetime. What kind of leather collar will fit your Labrador perfectly? In general, thicker collars will provide more support, making them ideal for growing up stronger dogs. Wider collars are also more comfortable because they will reduce the pressure on the neck. A collar for puppy should be lightweight and not very wide. And, of course, you should make proper measurements to order a correct size that will fit your canine.
