My Australian Shpherd is 52-53 days pregnant this is her first litter over the last 24 hours her temperature started at 100. 3 spiked up to 100.9 and has now dropped down to 99.7 she has milk coming from her teats as well as a pretty big chunk of clear mucus like discharge hanging from her vulva could this mean labor really soon?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! It could mean labor is soon. Mild can come in days to a week before labor. I'd want to see the temperature consistently stay lower. If it does it should mean stage 1 labor should begin in 24 hours. I just want to be sure you have confirmed pregnancy. If not then keep in mind pseudopregnancy and an infected uterus. I've attached a handout I provide for my clients. Good luck! Stages of Labor: -Stage 1 tends to start 10-24 hours after temperature drop (usually below 99 F). -Stage 1: nesting. Can persist for 3-24 hours before abdominal contractions begin -Stage 2: Visible abdominal contractions. FIRST PUPPY SHOULD ARRIVE WITH IN 1-2 HOURS. -Stage 3: passage of placenta. Usually occurs within 15 mins of passing puppy. If it does not happen, don’t worry. When to worry/Call: -Strong contractions > 45-60 mins without birth of a puppy -Weak and infrequent contractions >4-6 hours without birth of puppy ->4-5 hours between puppies (after birth of first puppy without birth of the next puppy). On average a puppy is born every 45-60 mins. HOWEVER, the mother can often rest for several hours between puppies. This rest period is NOT associated with contractions and usually doesn’t exceed 4-6 hours. -If one puppy is born and she is having VISIBLE contractions for >2 hours without 2nd puppy. Recommend calling around 1 hour mark to talk to someone. -Failure to enter active labor (contractions) 24-36 hours after rectal temp falls below 99 F -Mother is in obvious pain: biting at vulva, crying) -No puppy within 2 hours of seeing green vaginal discharge -No puppy within 1 hour of seeing clear fluid from vulva (rupture of allantochorion) -No puppy within 1 hour of seeing a clear/water filled balloon at vulvar lips (puppy is in birth canal)
