Does my pup poop and pee to get treats?

I know it sounds like a silly question. It's his behavior that I have been observing since yesterday.

So, my puppy, Milo was brought to our home just yesterday. He seems like a very smart pup. He makes poo and pee accidents on the tiled floor sometimes, but most of the time, he poops and pees on the same spot, on the newspaper.

I actually don't have much money right now to buy the pads </3 Although some are sold cheap, it can be expensive if I have to use three or four pads a day so I'm using newspaper as an alternative and so far, there's no problem with it.

To train Milo to do his business on the same spot everyday, I offer him treats after the good deed. He likes those veggie biscuits that smell like milk. He goes crazy for it!

And before he does his business, he becomes super hyper. Just like any other dogs, he'd sniff and smell the floor first before moving to the newspaper. Then, he'd happily jump and hop and skip, before standing still to pee or squatting to poop.

Afterwards, he does the same thing again: jump, hop, skip around! And then he'd run towards me like he's expecting something!

Do you think I'm bribing him so much? Do you think he's doing all these things (pooping and peeing all the sake for a piece of treat / doing business on the same spot) ONLY because of these treats?

I worry he might stray from this habit if I stop giving biscuits...
