Bicheon crying

Question
My dog has been crying for 2 days.  She carries a toy in her mouth and just whines and cries constantly.  I have tried holding her, comforting her and she will not stop.  She also tries to bury her toy.  I let her and she still cries.  Thanks for the help

Answer
Is your dog spayed, and if not, how old is she?  Some intact bitches have false pregnancies and they may exhibit similar behavior.  However, because I can't see your dog, and she's obviously in some kind of distress, it would seem prudent to call your veterinarian.
