Hot dogs are fucking gross though. It's already hard enough to drown them in enough sauerkraut, mustard, onions, etc, to make them choke-downable. Hamburgers are different, it's actually (usually) reasonably good meat as a base, doubling it makes sense.
I CAN'T BE STOPPED! I WILL SHOVE TWO HOT DOGS IN MY MOUTH INTO MY CHEEKS LIKE A COLD MEAT EATING GERBIL. CHEEKS PUFFED OUT, CHEWING, STARING AT ANYONE WATCHING AND NEVER BREAKING EYE CONTACT.
So I don't think you're wrong, but I also suspect you haven't had an all-beef hotdog. Like the Costco hotdog. It's a very different dog, higher quality & uniform meat. Better texture. You should give it a try!
