My dog has been acting really weird since Saturday afternoon before I began to feel early labor signs all he would do is cry and wanted me to carry him and when I would put him down he will just go crazy I when to the hospital and everything is okay baby is healthy so they send me home but since then he wouldn’t leave my side and all he wants is to cuddle next to me or my stomach and will cry bloody muttered if he can’t be with me has any one else experience this with a pet and could it be a sign of something
