I tried everything, my dog has very few chips, but as she is allergic, it only takes one or two to his hair starts to tarnish and she lost them. Finally this necklace is the most economical, quiet for six months, his hair has regained all its brilliance, she scratches a bit but I think it is more related to the collar that should cause little irritation, see ... Contrary to what some say, this is also good on the chips, there are 2 different names necklace but it is exactly the same product that is broadcast.
