Why not? Pigeons can sense the Earth's magnetic field and navigate by it. Why wouldn't a dragon? And given that the dragons have rather more capabilities than pigeons...why wouldn't they be able to sense subtle changes in gravity?

And I'm not saying that they necessarily perceive these things consciously. Many varieties of life on Earth are effected unconsciously by the tides, the weather, and the seasons (including humans). So, I say, why not? It's a simpler explanation than many others.
