Dogs intuition??

I’ve heard of people whos’ pets get super clingy once they are confirmed pregnant. But has anyone heard of their pets doing it straight after ovulation??

When my hubby and I got together he had a dog. Who I have always loved as my own and he has loved me the same. However usually he is he kind of dog who sits around and watches you walk from room to room until you open the fridge. But for the last 2 days he has followed me like a shadow non stop. Won’t go to my hubby when when he is being called because he won’t leave my side. Even crawling up onto the recliner (he is a German shepherd x kelpie mind you) when my hubby calls him for cuddles.

Could it be that he knows something I don’t know!?
