To clean your dog's collar, kindly adhere to the following steps: Combine lukewarm water with a gentle detergent or pet-friendly shampoo in a bowl or sink. Immerse the collar, using a soft-bristle brush or sponge to scrub, paying special attention to any soiled or stained sections. Thoroughly rinse the collar with water to expel all soap residues. Allow the collar to air dry entirely prior to its next use.
