Is puppy regret actually common, or is it about expectations?

I’ve been reading quite a few posts here about people struggling or regretting getting a puppy, especially once they reach the teenage phase. A lot of it sounds like feeling overwhelmed by the amount of work and how much it changes day-to-day life.

I don’t have a puppy yet, but I do work from home and I’m trying to learn as much as I can before making the decision. I’m honestly just curious, is this experience pretty common for most owners, or are there things that make it feel harder (like expectations, routine, or lack of support)?

Not looking to judge at all, just trying to understand what’s normal and what can realistically be prepared for beforehand.
