Our collars are lovingly handmade! This collar is made with sturdy nylon webbing with and then finished with side release buckles and a heavy duty D-ring. Stress points where the buckle attaches to the collar have reinforced stitching. Please use the following guide to help determine the appropriate fit for your furry friend. Please use a tape measure to measure your pet’s neck where a collar would lay. A collar should be loose enough that you can put a finger between the collar and your dog’s neck. But, not too loose that the collar can slip over your pet’s head without being unbuckled. All collars have the option to add a leash with the same pattern. Collar care: Hand washing in cold water is recommended and then lay flat to dry. Each collar is individually made in a smoke free, but not pet free environment.
