    Chain Reaction Dog Collar

    Replaces my old leather and slightly rusty chain collar. Fabulous easy wear, great training tool and looks super. Better than leather as it dries quickly when wet. Stylish highly recommend

    Beautiful collar, but it turns my white dog's fur black :(

    I love the collar and it works really well but the metal must be cheaper or have some alloy in it, because it rubs off into my white dog's fur. Will likely be looking for a refund unfortunately. Beware owners of white/cream coloured pups! Other chain collars have not done this to my dog's fur.
