They're a cute and popularized breed, but with any dog that has a very... stylized? structure you're usually gonna run into health issues because of how they look. Whether it's a HUGE dog with lots of skin rolls or a tiny dog with a flat face.

At the end of the day, dogs still need homes! But if you're planning on owning one it's important to know what medical bills you might be paying and how it can effect their life style. Different behavioral and developmental risks should be looked into as well, I know dachshunds can run aggression risks if undersocialized and also might have more exercise and mental stimulation needs than people usually suspect. Ours was quite smart hahaha.
