Do they have puppy burgers?

White Castle does

If you give your puppy a burger, I'm sure that he will eat it!!!

I don't know what a puppy burger would include but I'm sure you can get a flying Dutchman and your puppy would enjoy it

I have no clue.

What is a puppy burger? I think they serve beef not k9 or cat????

That's totally true

Customers can order a Pup Patty from In-N-Out and will be given a perfectly grilled hamburger patty served entirely plain—without any toppings, condiments, a bun, or even salt. While it might sound unappetizing to us, dogs find the Pup Patty irresistible, and it's, in turn, a great source of protein for them.
