Puppies love to explore and play, but they can also be very mischievous and get into trouble if not properly supervised. To keep a puppy away from the Christmas tree, it's important to provide him with plenty of toys and activities to keep him occupied. Make sure to provide a variety of chew toys and treats to keep him entertained and out of trouble. Additionally, make sure to keep the tree out of reach and in a safe place where the puppy can't reach it. Lastly, keep an eye on your puppy at all times to make sure he doesn't get into any mischief.
