Say goodbye to your furry friend’s skin and joint problems with the Pupca Cold Laser Red Light Therapy Brush for Dogs & Cats. This innovative brush features 40x 660nm and 8x 650nm laser diodes that penetrate fur with the help of light-guiding teeth. This allows the red light and laser light to fully reach the skin and deep tissues, providing relief from itching, hot spots, infections, arthritis, and joint pain. This versatile brush is great for both kitties and pups, and it’s conveniently portable so you can bring it along when traveling. Best of all, light therapy is a great way to ease your furbaby’s skin conditions, soothe joints and deep tissue pains, while grooming.
