All You Need to Know About Maternal Aggression in Dogs

Mother protecting puppies

Some studies show that maternal care has a significant impact on individuals’ development in many species.

That conclusion is substantial, especially to mammals. Humans, pigs, cats, monkeys and dog behaviors, habits and cognitive abilities are sharply defined by maternal care in the early stages of life.

When it comes to newborn puppies, maternal care is provided by the dam, who gives food, shelter and warmth to the offspring.

She protects puppies from potential predators, helps them survive and grow safely.

Maternal behavior commonly seen among dogs includes licking, nursing, play, contact, and punishment.

In some cases, the feeling of protectiveness might reach high levels in the dam.

According to experts from the Pet Place, that is when the syndromes can be called the ‘maternal aggression’.

A dog experiencing it will change from a previously adorable and friendly pet into an unapproachable animal.

A special bond is created between the mother and the offspring due to the release of oxytocin – a ‘bonding hormone’.

Moreover, the high levels of progesterone, experienced during pregnancy, fall rapidly once the puppy is born.

At the same time, the levels of estrogen, the activating hormone, rise drastically.

With all the chemical changes occurring in the dog’s body, no wonder some mothers feel overprotective and not at ease.

If you are the lucky owner of a female dog who has just given birth to several cute puppies but doesn’t let you come to her babies, then you are in the right place.

In this article, you can read about maternal aggression in dogs and learn how to manage it properly:

Place Management and Safety

isolated environment for the dog and the puppies.

During this time, your dog may start feeling uncomfortable in your house. You must establish a safe, quiet and preferably isolated environment for the dog and the puppies.

Mother should feel as safe as possible. In this time, she will want to “fulfil her maternal duties” and focus on the puppies exclusively.

Try to avoid sharing the good news about newborn puppies with all the people you know. Your friends will most likely want to see, touch and play with the offsprings.

While it may be okay if your dog is calm, once it experiences maternal aggression, the presence of any unfamiliar people will only make the dam more hostile.

Also, try to keep small kids away from the puppies. It may be fun for them to see and play with the little dogs, but it will be extremely stressful for the mother.

The dog, even if it knows the child from before the pregnancy, may develop a sudden feeling of aggression oriented towards your kid.

Don’t Impose Too Much

You may want to help your dog take care of her puppies. No matter how good your intentions, if your dog has maternal aggression syndrome, you should let her be instead of trying to interact with her too much.

The mother dog may refuse to go outside and leave her offsprings, drink or eat.

If it happens, try to understand that she is simply worried about her puppies.

Don’t force her to go out on prolonged walks, leave the safe space for no reason, and eat if she doesn’t feel like it.

You will help her the most if you look for the signals she will give you.

If she wants to interact – interact, if she doesn’t – leave her and the newborn puppies alone.


dog spaying

If your dog has developed intense maternal aggression after giving birth to the puppies, you might want to start considering spaying. The surgery is safe and effective.

Spaying will prevent your dog from experiencing maternal aggression in the future. If you are having moral doubts, listen to the experts.

Most of the breeders say that if a mother has maternal aggression, she should be separated from the breed and then spayed.

It might turn out to be the best possible solution for everyone.


Maternal aggression is a short-term syndrome experienced by the dams after giving birth to the puppies. It doesn’t mean your dog turned from a beloved pet into a wild animal that will never be trained again.

It only means that your pet is experiencing profound chemical changes in the body.

These changes are needed in order to provide the best chances of survival for the individual puppies and the whole species.

As a pet owner, you should accept them and help your dog go through this challenging time.
