The dog’s aggression after a new baby can be triggered by many things. We will look at some of the aggression triggers below.

The smell

A baby will have a strong smell. It is an easily distinguishable smell that anyone would know that is a child. The problem is that dogs tend to have a strong sense of smell thousands better than that of humans. With the new baby scent, sometimes the smell can be overloading on the dog’s senses.

It is estimated that a dog possesses up to 300 million olfactory receptors as compared to humans who only have 6 million of similar receptors. It is why dogs can pick up scents better.


Other than being able to smell better, dogs can also hear better especially the high-pitched sounds. A dog can hear within a frequency range of 40 to 60,000 Hz, while for a human that range is 20 to 20,000 Hz.

A baby is likely to cry most of the with a high-pitched sound. With the high pitch, a dog is likely to get excited and misinterpret such sounds to a prey. Any tiny squeals from a baby will get the dog excited all for nothing.

Babies like to stare

Dogs always stare into their competitors in the eye in the wild to assert dominance. As we all know, babies can give you quite the stare. Whenever they stare too long at a dog, it might think it is a sign of confrontation.

It is not just for babies, but also adults. For a dog that you do not know or rarely get social with, staring at it might seem threatening to it. With a baby, it is worse because your baby has no idea that he or she is provoking the dog.

Baby movements

Babies sometimes can be quite the unpredictable lot. They will run around, squeal, raise hands, and so much more. Such movements might not be ideal when around a dog. It might get confused not knowing how best to interpret the behavior. The worst is when children run around stepping on the dog’s tail. This is always going to make your dog more aggressive.

Unfamiliar face

For a dog that has not been around babies before, their unfamiliarity might cause a problem. Babies smell strange, make strange noises, and sometimes their movement is erratic. At this point, the dog might be confused and tries to be aggressive as a way of showing dominance.

For most dogs, whenever they see something new, they get curious, grab it, and drop it to see how it reacts. It might just do that around your baby, so be careful with it.


Can a dog really get jealous because of a baby? Well, think of it this way, you have always been the center of attention, but suddenly that changes when the baby comes along. The parents now spend more time with the baby than you. This results in differential treatment. Well, it is easy to see why a dog might get jealous of the baby and hence show aggression.

Type of breed

What you need to understand is that some dogs might be good around kids while others not so much. The next time you seek to adopt a dog, make sure it is one that can behave well around kids. Talk to the animal shelter staff to help you understand what type of dog you are getting to avoid putting your child at risk.
