Available in Small, Medium and Large Sizes, we have Pink, Blue, Green and Red Collars available, although our personal favourite is Red or Green. However, whatever your choice is, they are vibrant and bright and can help take some of that fear away when walking your dog. We have all been there, your dog is off the lead and runs off, and you are calling them and worrying where they are, and this can quickly turn to panic if they don't respond. Thankfully most of the time, they are exploring a new smell or maybe conducting their business. With a flashing dog collar light-up collar, you won't have to worry anymore, you will be able to see them, and I mean really see them. As dog lovers at Ultra, we have six that's six dogs. Each of our glow in the dark dog collars comes complete with a micro USB charging cable and can offer up to 10 hours per charge from 2 hours of charging. They are also a reflective dog collar with reflective strips down either side, so they can provide safety protection for your dogs even when turned off. Waterproof, they are resistant to wet and cold weather conditions.
