Many mother dogs display behavioral changes after giving birth, and these can range from mild to extreme. Depending on the cause, uncharacteristic dog behavior after having puppies rarely lasts more than a few weeks before a new mom begins acting more like herself again. The trick is understanding how to deal with the changes and care for your pet in the meantime.
Dogs Can Become Aggressive After Having Puppies
Aggressive behavior after giving birth is usually the result of a female’s instinct to protect her pups. The behavior you might see can range from showing her teeth and growling to outright biting. This behavior usually appears within hours of giving birth, as the new mother focuses on caring for her litter. She’s tired, her hormones are fluctuating, and she may still feel some discomfort after the birth, so displaying a little aggression is fairly natural, even though it’s unpleasant.
To keep aggression to a minimum:
- Try not to handle the new pups more than necessary. Let your dog do her job with as little interference as possible for the first week.
- Keep other people away from her whelping area, especially people she doesn’t know. It’s difficult to resist showing off the puppies, but there will be plenty of time for that later when they are about 6 to 8 weeks old (after they are vaccinated).
- Keep other pets away from her and the puppies for the first several weeks. This includes other dogs who may have been her housemates. New motherhood trumps old relationships, but things should return to normal once the pups are self-sufficient.
- Avoid startling her, and talk to her in a calm voice as soon as you enter the room where her whelping box is located.
Aggressive behaviors usually begin to disappear within a week or two after delivery. If you feel unsafe around your pet, give your veterinarian a call to find out if an exam and some medication might be in order.
Dogs May Experience Anxiety After Delivering Puppies
Anxious behavior is not quite as concerning as aggressive behavior, and it’s not uncommon for a female to display some anxiety after giving birth, especially if it was her first litter. She may whine and tremble if someone comes near the pups, and she may even become a bit clingy with her primary caregiver. She may also tend to lick the pups too much, which can leave them wet and chilled.
To help reduce anxiety:
- Talk to the dog in a calm, reassuring voice and keep the activity level in the room low.
- Feed her some high-quality canned dog food. A full stomach may help her relax and settle in with her pups, and the extra moisture in the canned food will help her produce milk.
- Softly praise her when you see her caring for her pups, such as nursing or cleaning them. This will let her know she’s doing the right thing. If she cleans and licks them too much, distract her from this task for a while by stroking her head and talking to her. This may help her relax and let the puppies settle against her for warmth.
Most new moms settle down within a day or two of giving birth as they get used to their new duties, so it is usually not necessary to call the vet unless the anxiety seems excessive. If your dog is especially restless and trembles constantly, these could be signs of eclampsia, and she needs to go to the veterinary clinic immediately.
Dogs Dig Outside of the Whelping Box
It’s natural for a female to dig up the paper and blankets in her whelping box as she attempts to make it more comfortable for her and her new pups. If she begins digging outside of the box, however, this can be an extension of anxious behavior. Typically, it’s a sign she feels her pups need to be moved to a more secure place.
If that’s the case, she’ll search for a secluded corner, a family member’s bed, the inside of a closet, or some other out-of -the-way place, and begin digging to create a new nest to transfer her pups. To avoid this behavior before delivery, select a quiet, low-traffic area to set up her whelping box before she’s ready to give birth. This gives her time to get used to the spot and feel more secure when it comes time to deliver her puppies.
To properly manage the behavior:
- Leave her alone with the pups as much as possible, and keep strangers and other pets away from her and her litter.
- Take her outside for a quick trip to relieve herself and get some fresh air. The activity may help her settle in better once she’s back inside with her pups.
Digging and trying to relocate pups tends to stop as soon as the female feels more secure, so address this issue as quickly as possible.
Watch for Displays of Lethargic Behavior
Some females are perfectly calm and easily settle into caring for their pups, but lethargic behavior goes beyond being calm. A lethargic female will behave sluggishly and neglect her pups. She may even lay on them and accidentally smother them.
An infection, such as mastitis, or some other post-delivery malady can cause lethargic behavior. If your dog becomes lethargic, place the puppies in a warm box to protect them and take her and the pups to the vet immediately for proper diagnosis and treatment.
Manage Your Dog’s Accidents
House accidents tend to happen for several reasons. A female may feel too weak and tired after giving birth to go outside to relieve herself, and she may also feel anxious about leaving her newborn puppies. Continued and frequent house accidents could also be a sign she has developed a urinary tract infection after giving birth.
To properly manage this issue:
- Spread newspapers or puppy training pads on the floor around the whelping box, and plan to clean up and replace them as soon as she soils them.
- Offer one of her favorite treats to try coaxing her to go outside for quick trips to relieve herself.
- Have her examined by a vet if she has frequent accidents for more than a day or two after giving birth.
If there isn’t a medical cause for the house accidents, this behavior normally disappears within a few days of delivery, after the female realizes it’s safe to leave her pups alone for a few minutes while she goes outside.
Be Aware a Mother Dog May Eat Her Pups
This is a very disturbing behavior that you hopefully will never face. In rare instances, a new mother will kill and eat her pups, and this can happen no matter how docile her typical behavior is. VCA Hospitals attribute this behavior to a primeval, protective instinct that can be triggered if the mother thinks her pups make too much noise and might attract predators.
In a case like this:
- Remove any surviving pups and keep them in a box on top of a heating pad set on low.
- Only put them with their mother for supervised periods so they can nurse. Keep a very close eye on her, especially if she begins licking them, because a single bite can kill.
- Clean the pups yourself with a warm, wet cloth to make sure they urinate and pass stools until they are old enough to eliminate without help.
This behavior generally occurs within hours or a couple days of delivery while the pups are still newborns, and you should call your vet immediately after any surviving pups have been separated from their mother.
Once a female has cannibalized her pups, it’s best to avoid breeding her again because she will likely repeat the behavior. After the pups are running around, you can try keeping them with their mom for supervised periods to see if she will accept them.
Signs It’s Time to Call the Vet
A post-pregnancy exam can reduce or eliminate medical issues that could cause a drastic change in the new mom’s behavior. Cleary Lake Veterinary Hospital in Prior Lake, Minnesota, recommends that all females see a veterinarian for examination within 48 hours of giving birth. This is to make sure all puppies have been delivered, and the uterus is shrinking back to its pre-pregnancy size. In many cases, a vet will administer an antibiotic injection as a precaution against infection.
Even if your female had a post-pregnancy exam, she could still display some worrisome behaviors. You should call your vet if she:
- Appears especially anxious
- Has a temperature higher than 102 degrees Fahrenheit
- Isn’t able to settle down with the pups
- Refuses to nurse the pups
Keep an Eye on the New Mom
Hopefully, you’ll never experience any serious behavioral changes after your dog has puppies, but keeping a close eye on her for the first week after delivery should help you spot problems and address them as they come up. Don’t hesitate to consult your veterinarian if you feel your pet’s behavioral changes are more than you can handle.
