Mucous

Question
My english mastiff is 58 days pregnant with her first litter and 2 nights ago I noticed she was leaking mucous and last night today it has turned into more of a whitish watery discharge then thesnotty lolling stuff. Her temp had been in the 99's for the past 6 days. What does this mean? And when will she go into labor?

Answer
She is probably getting close to coming into labor. Gestation is till day 63, so ideally you want her to get to that day. Mucus is quite common, and is the early sign of labor. Once her temperature drops to 98 and she begins to den and burrow, you will know she is going into labor. Once her contractions start you will be able to see when she is in labor.
