Using your Perri's Padded Leather Dog Collar is easy. Just fasten the roller buckle around your dog's neck. Make sure it's not too tight or too loose - you should be able to fit two fingers between the collar and your dog's skin. When it comes to maintenance, use a soft, damp cloth to wipe the collar clean. Avoid using harsh chemicals as they can damage the leather. If the collar gets wet, let it dry naturally away from direct heat. Also, regularly check the buckle for any signs of wear and tear. If you notice any issues, replace the collar to keep your dog safe and comfortable.
