Is my whelping box heater delaying my dog's labor? She's overdue!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Your Vet is correct! The average length of a canine pregnancy is 60-63 days. We consider dogs overdue if 72 days. If she is acting fine and you are monitoring her temp just continue to watch her. Here are some tips: 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) Good luck!!

A dog's pregnancy lasts between 58-68 days, so it is possible she could go into labor anytime after that. I would start taking her temperature rectally twice a day. A dog's normal temperature is between 101-102.5F. Once it drops below 100F, she should give birth to her puppies within 24 hours. Should 24 hours pass after this temperature drop with no sign of puppies or she reaches 69 days of pregnancy without going into labor, she will need to see a vet immediately. Best of luck, I hope this helps!

Dogs will gestate anywhere between 58 and 68 days. Typically, the progesterone level will drop to around 2ng/ml about 48 hours prior to labor and then again to 1ng/ml about 24 hours before labor. You should also monitor her temperature. Labor typically follows within 24 hours of a drop below 100 F. If your vet is not concerned, be patient. Bella is almost there!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Kalani Breeze. If she conceived on that first mating, she would be about 56 days pregnant. This is a little early to go into labor, but it could be possible. Keep an eye on her over the next 24 hours. Should they pass with no sign of her going into labor, have her checked out by a vet to be safe. I hope this helps!

Hello. Dogs are pregnant an average of 63 days, so your girl is probably due any time now. If she is acting relatively normal, just give her a little more time. Keep a mental note on how much movement you are feeling in her abdomen & if it begins to diminish, or she acts lethargic, ill, vomits or develops a dark discharge from her vulva without going into labor, see your vet immediately. She may need a C-section. Otherwise, your dates may be off a bit & labor will proceed when her time is due. Thanks for using Petco Pet Education Center, formerly Petcoach.

This temperature isn't enough of a drop for me to think labor is occurring. It would be down around 99-98F. At 56 days, yes it is still a little early, but because a due date isn't an exact science, more of a guesstimate, it could happen. A dog's normal gestation length is 58-68 days, and if 68 days pass without a sign of labor, I would take Sissy into the vet.

It sounds like Harley is preparing for birth. Average gestation is 63 to 65 days , but parturition (birth) can happen anytime from 58 to 68 days. When the temperature drops by about 1 degree Fahrenheit from her normal temperature you can expect her to give birth within 24 to 48 hours. This is not a 100% surefire determination, so do not panic if it takes a bit longer. Watch her for building a nest, dripping milk, and general nervousness. These will also be signs of an impending birth. Here is some useful information: https://www.petcoach.co/article/whelping-giving-birth-in-dogs/
