I have a pit bull and the past couple of days she's been abnormally clingy and cuddly. I love it but she's not normally like this. It's like she can't be more than a few feet away from me at a time. And I believe I've been having pregnancy symptoms. I read that your dog can tell if you are pregnant and be really clingy, could I be pregnant? Anyone else's dog do this right before you got your BFP?
