This handmade dog collar with Optional flower or bow tie is made out of a blue and lime green plaid 100% cotton fabric. All dog collars are sewn on black polypropylene webbing for added strength and durability. I use a nickel plated d-ring, plastic triglide slide and a quality contoured side release buckle that is designed to hug your dogs neck. The matching green flower and bow tie is handmade and removable. The bow tie and flower are attached with a double sided Velcro that wraps around the dog collar for easy on and off.
