"Do you like my white horse?"

Mod

The possessive determiners mein, dein, sein, ihr, unser, euer inflect like ein and kein -- and so they have no ending in the nominative or accusative case for neuter singular nouns. (Nor for masculine singular nouns in the nominative, e.g. ein Junge, mein Saft.)

Just as we say ein Pferd and not eines Pferd, so we also say mein Pferd and not meines Pferd.

Isn't Pferd neuter?

Mod

Yes, Pferd is neuter. I'll edit my comment.

Is there any reason why "Gefällt dir mein weißes Pferd?" should not be accepted?

Mod

No; it's fine. Just a forgotten alternative; I've added it not.

So I also answered in that way, and just out of curiosity, which way is more generally popular to say something like this, with gefallen or with mögen?

Mod

gefallen is generally about liking the visual appearance

mögen is more general

So Gefällt dir mein weißes Pferd would imply that I'm asking if you like the horse's white appearance (especially since it was mentioned)?

And magst du mein weißes Pferd would imply do you like the horse in general?

And if so, could the mögen one also overlap onto gefallen to mean physical appearance?

The appearance in general, not necessarily the white colour.

Perhaps they like the shape of the neck as well.

And magst du mein weißes Pferd would imply do you like the horse in general?

Yes, pretty much. Could be its character, for example.

And if so, could the mögen one also overlap onto gefallen to mean physical appearance?

Hm, not so sure about that. If I'm asking about appearance, I think I'd prefer gefallen or at least the even more general Was hältst du von meinem weißen Pferd? "What do you think about my white horse? What's your opinion about my white horse? How do you feel about my white horse?"
