Okay ive been pregnant for 10 weeks and my dog has been attatched to me but last few days shes been acting really strange growling at the door in my bedroom and going all stiff, shes a timid dog but has been 10x worse over the last few days being afraid of every noise there is. Could a ghost have came into my house too protect the baby or whats happening with my dog? Shes only 7 months and i feel like im going crazy
