Unlike our Reflective collars the Glow collar absorbs light from any source, and will glow in the dark for up to 30 minutes. They reflect as well and are ideal for seeing your dog in fields or wooded areas when out walking. Available in 2 sizes 61cm (24″) and 71cm (28″), the highly effective glow material is stitched along the middle of the Polypropylene webbing and finished with stainless steel Delrins and Nato Spec plastic clips.The 40mm wide webbing helps flatten the fur on long coated dogs enabling the glow material to be seen.
