Custom sized Bolos are available in most of the leather used for the other Bolo collars on this site. You will be prompted for sizing and color upon checkout. A bolo tag collar is a lightweight alternative to nylon or heavy leather, buckle collars when your pet does not need to be restrained. It is worn like a “necklace”; low and loose. Bolo Tag Collars are NOT meant for restraint or to be attached to a leash for walking - EVER - as they could break. However, they should be fine for everyday use, inside the home or in the yard, to hold tags or collar charms.
