Simply as the title says: I have a dog and the only thing he ever was noticeable for me was, when blocking passages I wanted to pass.
So is it anything usefull for except showing me a heart over his head when clicked?
If not so: How to get rid of it?

Pets currently have no purpose (except making you go d'awwwww when you get it). It's been request by the fanbase that they be given a purpose in a later update, and the developer is considering adding new ways to interact with them (though note that "interaction" doesn't necessarily mean "purpose").
Rather than a purpose though, it does have one minor effect:
Apart from those, currently the pet has mostly vanishingly subtle, subjective, or aesthetic purposes:
It gives a new farm a sense of activity and life, which was the original purpose:
It gives you an early lesson in how the game's animals work, before you have ones you need to take care of (i.e., that they block your way, they can be pushed if there's room, they're sort of random and not very fast, short ones are easily visually lost in grass, they won't damage your crops, they can be interacted with, etc.)
There's currently no way to get rid of your pet, and I get the sense that the developer has no intention of making it possible.
