Aloha,
There are some Dog Owner's that think "Jumping" is a cute "Trick or habit,
No matter what size your Puppy or Dog is......it is still "Dangerous"! Just think if you condone this? What's to STOP it from jumping out of the Car, while moving or even Parked still? Or jumping off of anywhere? After all in their mind
it's OK. with you to jump off the Bed or Couch, they don't know what is Safe for them or not? This Breed is Fearless.........you'll learn your lesson after they
break a Leg, GOD Forbid! IMO it's easier to buy a set of Stairs and start Training your Puppy to use them, better Safe than Sorry?
