In-N-Out is known for its secret menu. So much so that the secret menu doesn't seem so "secretive." Despite being so well-known, many people are surprised to find out that In-N-Out's special menu includes an item for dogs. It is called the Puppy Patty and features a plain hamburger patty without any salt added that is served in a doggy bag (AKA a paper bag). What dog is not going to love that?! I mean, just look how happy the dog is below with his In-n-Out Puppy Patty. The prices for a puppy patty do vary by location with some In-n-Outs charging a buck or two while others may even charge you the price of a regular hamburger. Regardless of the price you are charged, your dog is sure to love it!
