Reasons of 3 month old puppy biting:

Puppy biting can be caused by a variety of variables, so there isn’t one clear reason why a three-month-old puppy bites. Sometimes it may be due to people’s animal-aggressive natures. Other times, it may just be a puppy’s natural habit. The reasons are briefly discussing below:

A natural defensive process:

When pups are three months old and still developing, it is normal for them to bite people. By biting, they defend themselves. 

When something threatens their comfort zone or they perceive it as detrimental to themselves, puppies defend themselves naturally by biting. 

When youngsters tightly embrace or kiss them without knowing their mood or level of comfort, they may bite humans in defense.

The eruption of new teeth:

During the development of a puppy’s new teeth, which begin to erupt at the age of three or four months, the development of the puppy’s mouth may get irritated, which may lead to the puppy biting its human companions. 

They act in this manner notwithstanding the circumstances.

Natural genetic phenomena:

As puppies learn from their ancestors, it’s possible that they acquire the habit of biting naturally at a genetic level. As a result, when an inappropriate action is taken against the pups, they bite. 

So they adopt this biting nature as a genetic phenomenon.

Over excitement:

They are little puppies who still haven’t learned to control their excitement. They are so naïve, get tempted easily even with tiny matters and out of joy they can start biting you. They may also want treats or praise out of excitement and bite. 

Out of fear and irritation:

Puppies have been known to bite humans out of fear and annoyance, especially when they are playing with children or humans who are acting erratically. 

Children frequently provoke puppies unintentionally while they are around them, which can irritate the 3 month old puppies into biting.

Want your attention:

Puppies always want love, affection, attention and praise from their owner. 

If they find you’re not focusing on them or doing other things for quite a long time, they may bite you because of some love, belly rub, or a physical touch like a hug or pat on the head.

Find any change in their routine:

Puppies are very much strict to follow their routine that they get by their ancestors or genes. They want the same thing you did for the last couple of days and any changes can make them confused. 

They can’t stay, start biting you because of wanting your time.

Is it normal for 3 month old puppies to bite?

Puppy’s development into a biter at month 3 is a natural process. The primary cause of biting is related to the development of their teeth, which irritates them and causes them to adopt this process of tooth eruption development out of irritability. 

In addition, their genetic composition predisposes them to bite when in danger or when they perceive a threat to their safety. It is also normal for them to bite someone who triggers them or pokes them. 

When they are with their fellow puppies, it is normal for them to bite and growl as a common phenomenon of communication.

Aggressive biting:

A three-month-old puppy can, in fact, bite forcefully when forced to do anything against their will or when a person’s brutal nature irritates them. 

Puppies will occasionally attempt to defend themselves by biting aggressively when they are terrified of other canines.

Biting and growling:

They get this quality from the moment of birth. Given that they use growling to interact with other dogs and express their feelings, three-month-old puppies would naturally do this.

Biting older dogs:

It’s normal for three-month-old puppies to bite older dogs when they play with other dogs and when they’re defending themselves in a dangerous scenario. However, they may end up getting hurt while defending themselves.

Biting me:

It is natural to get bitten by a three-month-old puppy. Some pups may bite their owners when their owners make an aggressive face hug or kiss attempt and fail to understand their body language.

Redirect to another thing:

Try to take their focus on other things while they try to bite using the redirection method. For instance, give them a toy, try to make it move and make it more exciting to them than biting you.
