Puppies chew while they are teething.
Keeping them safely crated stops them from chewing on electrical cords, swallowing objects that can choke or eating poisonous plants. Your puppy will get bigger, so buy a crate they can grow into. Put a pillow in back for a bed, and toys that are safe for entertainment. You can obtain a water bottle that hangs on the outside of the crate, or place a small bowl of water inside the crate. Consider allowing your pet on the furniture.
