Dogs acting weird

Ali

I’m 38 weeks today and my dogs are acting strange. One of them is always needy but today she keeps wanting to lay on my belly instead of next to me. And the other dog who hasn’t paid a bit of attention to my belly or me this entire pregnancy, started licking my stomach like crazy! I know dogs can sense things and I’m wondering if labor is near? Haven’t had any signs whatsoever but maybe they know something I don’t.
