Anxiety and Fear are different but related emotions. What breed is this. How old? (6 what, months or years), How long have you had him, where did you get him, any obedience training? only dog or with others? what is he afraid of? what situations? what have you done to help him with this?
Count the days from breeding. usually 60 to 62 days. Discharge can be "normal", but actual bleeding is probably not a good sign. In any case I would have her examined right now.
