Can your pets tell yet?

Carey
Just wondering if anyone noticed if their pets have acting more protective or stuck to them and how soon did they? I'm 16w 3d and this is my first pregnancy. I have 3 dogs (along with tins of birds, a tortoise and chinchilla ) but out of my dogs only my Pomeranian is different. He is my spoil baby, but he never let's me out of sight now. I started noticing at 7 weeks.
