The necklace ensure both comfort and durability of your best friend. The necklace is crafted in a classic style with a modern twist. It features solid moulded brass details that ensure its beautiful expression in all kinds of weather. It can be adjusted to fit perfectly around the neck, and is designed to be easy to handle. We recommend that you adjust the collar so that you can have 1 finger in between, so as not to cause irritation in your dog. It should not sit too tight, but also not be possible to get over the head of the dog. The collar is also equipped with a plastic buckle which makes it easy for the dog to walk around with.
