A dog that has just given birth looks noticeably different from her pre-pregnancy self. Her belly will be loose and saggy, her nipples enlarged and swollen with milk, and she’ll likely have a greenish vaginal discharge that shifts to reddish-brown over the following days. She may be panting, trembling slightly, and completely focused on her puppies. All of this is normal.
Her Belly and Body Shape
Don’t expect your dog’s abdomen to snap back right away. Even after all the puppies are delivered, her belly will look deflated and hang loosely. The uterus remains dilated and swollen during the first week postpartum, and it takes time for the organ to shrink back to its normal size. Most dogs won’t regain their pre-pregnancy figure for several weeks, and some never return to exactly the same body shape, especially after large litters.
The skin along her underside may appear stretched, wrinkled, or saggy. Her flanks can look sunken compared to her previously round profile. This is all a result of the skin and muscle wall stretching to accommodate the puppies and then suddenly having nothing to support.
Vaginal Discharge Is Normal for Weeks
After whelping, dogs produce a vaginal discharge called lochia, which is a mix of fetal fluids and placental remains. It starts out greenish (sometimes dark green or blackish-green), then transitions to a red-brown color within the first day or two. This discharge typically lasts about three weeks but can continue for up to eight weeks in some dogs.
What matters most is the pattern: the amount should slowly decrease over time, and the color should progressively darken. It should not have a foul smell. If the discharge suddenly increases in volume, turns bright red, or smells bad, that points to a possible uterine infection. A yellowish-red or bloody discharge that persists beyond six weeks may indicate that the placental attachment sites in the uterus aren’t healing properly.
Swollen Nipples and Mammary Glands
Your dog’s nipples will be significantly larger than normal, firm, and warm to the touch as they fill with milk. The skin around them may appear pink or slightly flushed. This is healthy and expected. The mammary glands along her belly will feel full, especially if the puppies haven’t nursed recently.
Healthy mammary tissue should be soft to moderately firm, with a consistent color that matches the surrounding skin or appears slightly pink. The milk itself should flow freely and look white or slightly yellowish. Watch for changes that go beyond normal fullness: glands that turn red, purple, or feel hot and hard could signal mastitis, an infection of the mammary tissue. In early mastitis, the most common first clue is that puppies aren’t gaining weight normally, since the infected gland isn’t producing quality milk. In severe cases, the tissue can turn dark purple or black, and the milk may contain blood or pus.
Panting, Shivering, and Nesting
Right after delivery, most dogs pant heavily. This can last for hours and is a normal response to the physical exertion of labor. Mild shivering or trembling is also common and usually resolves within the first 24 hours. Your dog will likely be intensely focused on her puppies, licking them, repositioning them, and lying in a protective curl around the litter. She may seem reluctant to leave the whelping area, even to eat or go outside.
Her appetite may be low in the first 12 to 24 hours, then gradually ramp up significantly. Nursing dogs need far more calories than normal, so a return to enthusiastic eating is a good sign. Some dogs eat the placentas during delivery, which can cause loose stools or vomiting afterward. This is unpleasant but not dangerous.
Temperature and Energy Levels
A new mother dog’s body temperature typically sits around 38.8 to 38.9°C (about 101.8 to 102°F) in the first few days, which is within the normal range for any healthy dog. Some dogs do spike brief febrile episodes above 39.5°C (103.1°F), and research on healthy postpartum dogs suggests these short temperature bumps can be normal. However, a sustained fever paired with lethargy, vomiting, or loss of interest in the puppies is a warning sign of uterine infection (metritis) or another complication.
In the first day or two, expect your dog to be tired. She just went through a major physical event. She’ll spend most of her time lying down with the puppies. As the first week progresses, she should gradually become more alert and willing to move around, eat, and go outside briefly.
What Recovery Looks Like Week by Week
During the first week, the discharge will be at its heaviest, her belly will be at its saggiest, and she’ll be most intensely bonded to the whelping box. The mammary glands will be at full production. By weeks two and three, the discharge should be noticeably lighter and darker in color. Her energy levels should be approaching normal, though she’ll still be spending the majority of her time nursing.
Between weeks three and six, her uterus continues contracting back to its original size. The discharge tapers off and eventually stops. Her body will start to look more like herself, though her nipples will remain enlarged as long as she’s nursing. Once the puppies are weaned (usually between six and eight weeks), the mammary glands gradually shrink and the nipples reduce in size, though they often remain slightly larger than they were before pregnancy.
Signs That Something Is Wrong
Most dogs recover from birth without complications, but knowing what’s abnormal can help you catch problems early. Panting and restlessness that start or return days after delivery, especially paired with tremors, stiffness, or muscle twitching, can be signs of eclampsia (dangerously low calcium levels from milk production). This is a medical emergency that tends to occur one to four weeks after birth, most commonly in small breeds with large litters.
Uterine infection typically shows up within the first week. The classic signs are foul-smelling discharge, fever, loss of appetite, vomiting, lethargy, and decreased interest in the puppies. A drop in milk production can also accompany infection. Any mammary gland that becomes hard, hot, discolored, or painful warrants attention, as mastitis can progress quickly from mild swelling to tissue death if left untreated.
