No. Organ systems only develop in larger, complex organisms. E.g. amoeba, a single celled organism, is small enough that all its needs can be obtained by the relevant organelles through diffusion. A dog, a large multi-cellular organisms, needs a system to deliver its requirements to the necessary tissues .

No, organ systems are found in more complex organisms such as humans but organisms such as bacteria or paramecium lack organ systems.
