Using this dog collar is super easy. Just put it around your dog's neck and fasten it. 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 neck. When it comes to maintenance, keep it away from excessive moisture and dirt. If it gets dirty, you can gently wipe it with a damp cloth and then dry it thoroughly. Always check the collar regularly for any signs of wear and tear, especially around the fittings and the tag. If you notice any issues, it might be time to replace the collar to keep your dog safe.
