I have that one by the same seller (who i def recommend btw) for zeb its just tight enough that he cant get his head out of it but looks nice and loose when on in the house. Doesnt ruin the fur either around the neck as zebs got malamute type hair there (longish/thick/double coated) so normal collars make dents this one doesnt at all!
