We, at the Forest County Humane Society, pride ourselves on providing our animals with the best care possible, including the products we use daily. We are proud to support Canis Gear as our sole dealer of martingale, no-slip collars, leashes, training leads, muzzles, and many other products over the years. We not only use them daily, but we also send each dog home with one because we want to ensure the safety of a new adoption with a quality product that will help prevent an animal from back pulling, slipping its collar, and escaping. They make exceptional products, ship quickly, and I have never had any issues with anything. Bernie is an amazing person to run sales, and it helps us to stay stocked up on these products. Don't waste your money at Amazon or other places. This is the way to go. Thank you, Canis Gear, your products have helped us more than once work with fearful animals coming into a shelter setting.
