Yeah, if you have a lot of friends and tons of energy, level-up is just for vanity, and for your friends to be able to get juice/chips. Admittedly the cards are less useful if you don't need juice, chips or xp anyway, but you can also get coins from them.

Well, for the first 81 levels you also unlock the avatar shop items of course. But yes, level-ups or dogs are not particularly useful if you already have enough energy.
