Measure your dogs neck where the collar will naturally sit. Measure with a tape measure allowing two fingers to snugly fit between the tape and your dog's neck. No measuring tape? No worries! Just use a piece of string, then measure the length with a ruler.
Leather will patina with time and exposure to the elements. Normal wear will darken the leather as air, light, the oils of your dog's skin, and other environmental factors do their work, eventually developing into a rich tan colour. Prolong the life of the leather and hardware by keeping it away from water & chemicals. Nice Digs leather collars and leashes are not for swimming or water immersion.
Clean your leather collars and leashes with a soft, damp cloth. Nourish the leather from time to time, with a wax/silicone-free leather conditioner but patch test first before overall application as it may darken the leather.
