As a dog nears the end of her pregnancy, distinct physical and behavioral changes signal that labor may soon begin.
Early Physical Changes Before Labor
One of the first signs of approaching labor is a drop in body temperature. A normal dog’s temperature is around 101 to 102.5°F, but it can drop to about 98 or 99°F within 24 hours of labor. This is a reliable signal if you check regularly. Many breeders have monitored this daily over the last week.
The dog’s belly may appear lower as the puppies shift into position. This can happen 1 to 2 days before labor begins. You may also notice the nipples becoming larger and producing a small amount of milk. These are natural changes.
Appetite commonly declines. Some dogs may refuse food entirely in the final 24 hours. This is expected as the body readies itself for birth.
Vaginal discharge may also increase. Typically, this discharge is clear or slightly cloudy. If you notice green or foul-smelling discharge before labor starts, contact a vet immediately, as this could indicate a problem.
Behavioral Signs That Labor Is Near
Behavior changes are often easier to notice than physical ones. Many dogs begin nesting a day or two before labor by scratching bedding or creating a safe space.

Restlessness is very common. A dog may walk around, lie down, and then get up again repeatedly. She may seem unable to get comfortable. This is often one of the earliest behavioral signs.
Some dogs become more affectionate and seek constant attention from their owner. Others prefer solitude and may hide in a quiet corner. Each dog reacts differently. Pay attention to sudden changes.
Heavy panting and mild trembling may also occur. These symptoms can persist for hours before active labor begins. Remain composed.

Active Labor and What It Looks Like
Active labor usually begins with strong contractions. You may see the dog straining or pushing. This stage can last from 6 to 12 hours, depending on the dog. First-time mothers may take longer.
A fluid-filled sac may appear before the first puppy is born. This is part of the natural process. The puppy usually follows within 30 to 60 minutes after strong contractions begin. Timing can vary.
Once labor begins, puppies are commonly delivered every 30 to 90 minutes. Occasionally, there may be a longer pause between births; this is normal if the dog is resting and not displaying signs of distress. It is important to observe her closely.
Here are a few signs of active labor:
– Strong and visible abdominal contractions.
– Lying on the side while pushing.
– Fluid discharge before each puppy.
– Increased vocal sounds like whining or groaning.
– Focused attention on the birthing area.
Each puppy is generally followed by a placenta. The mother may consume it, which is typical. Consuming multiple placentas can cause digestive upset. Monitor discreetly.
Warning Signs That Need Immediate Attention
While most dog births go smoothly, certain warning signs warrant immediate action. If your dog has been straining for more than 30 minutes without producing a puppy, this may indicate a serious problem, and you should contact a vet right away.
A long delay between puppies is also a key warning sign. If more than 2 hours pass without progress and your dog shows distress, seek veterinary help immediately, as such delays can be dangerous for both mother and puppies.

How to Prepare for Your Dog’s Labor
Preparation can make the process smoother for both you and your dog. Set up a quiet, clean whelping area at least 1 week before the due date. This space should be warm and comfortable. Dogs prefer calm environments.
Assemble essential supplies ahead of time. Prepare clean towels, gloves, scissors, and a heating pad for the newborns. Having supplies ready streamlines the labor process. Attending to details is vital.
Stay close as the due date nears and check her temperature daily during the last 7 days to help predict labor.
Do not disturb her too much during labor. Offer support, but let her handle the process naturally unless there is a problem. It comes to giving birth. Trust the process.
Keep Keep fresh water available at all times. While your dog may not drink much during labor, having access is essential. Prioritize comfort and safety.ognizing the signs of labor in dogs can make a big difference in how smoothly the process goes.
From early physical changes to active labor signals, each stage provides clues about what is happening. Careful observation and preparation can help ensure a safer and calmer experience for both the mother and her puppies.
