Put in tiers for what kind of dog.

Cute friendly golden retriever: you pay extra.

Cupcake the chihuahua: you get a discount.

This has some minor issues, like people with pet allergies or who don't like dogs in general. I propose a dog plane, where all the middle seats have dogs. Additionally we can have a cat plane, where there's a bunch of chill kitties on the plane to curl up in people's laps

Yeah, fuck people with allergies! They dont need to fly anywhere ever again!

Swap that with a cat and I'm sold.

Am I the only one who isn’t a huge fan of dogs / pets in general? Everytime I pet someone’s dog or go to a house with a dog it’s always covered in fur slobber and grease from the fur. And after I pet the dog my hand smells awful

I love certain dogs, but the run of the mill pet on the plane is a bad experience. Either because of a bad pet, or a bad owner. Service animals are an exception, of course.

Well, they'd need to charge at least the full fare plus dog upkeep to break even.

As an aside, they enforce the rule that there's only one dog, cat or baby per set of 3 seats. This is because there's one extra oxygen mask per set of three seats.
Can you imagine if the air pressure was suddenly lost mid flight, and then you gotta get a freaking out cat out of its cage and hold a mask over its face? Has anyone actually ever done this and lived to tell the tale?

I'm not sure if people would enjoy flying in the cargo area. Even if there is a dog next to them. It would be easy extra money for the airline though.

As long as I'm not paying to have to keep away from your little toy I'm fine.

How much extra for a barkless flight?
