can nebody tell me what temperature my bitch should be prior to giving birth, she is 63 days but does not feel or look restless at all

Her temp. should be normally around 38.8 degrees.It usually drops to about 37.5 or below within 24 hours of whelping.
Don't worry about her going a few days over if she appears to be happy and healthy.
I had a bitch that went 6 days over her due date.She delivered 9 very strong healthy babies.

Good Luck!

Karen.
