It’s no secret that puppies are some of the cutest and most mischievous animals around. From the moment they enter your life, they bring joy and chaos in equal measure. But when it comes to behaviour, it can be difficult to know exactly when a puppy’s worst behaviour is likely to occur. Is it when they are still in their early months, or when they are a little bit older? In this article, we will look at what age is a puppy worse behaved, as well as the strategies you can use to help them learn better behaviour.

Behavioral Challenges of Puppies at Different Ages

Bringing a puppy into your home can be an exciting experience, but it isn’t always easy. As with any animal, puppies come with their own behaviors and needs, and it’s important to understand how best to care for them. One important factor to consider is age, as the age of a puppy can determine its behavior.

Puppies Up to 4 Months

Puppies up to four months are often the most difficult to train and manage. This is because they’re so young and have yet to learn the rules and expectations of their new home. During this time, they may act out by barking, chewing, and nipping. They’re also more likely to have accidents inside the house as they’re still learning appropriate bathroom habits.

In addition to being more difficult to train, puppies during this age are also more prone to separation anxiety. This is due to the fact that they’ve been taken away from their littermates and mother, and may be afraid of being left alone. If your puppy seems to be acting out due to separation anxiety, it’s important to provide them with a safe and secure environment, as well as introducing them to new people and animals slowly.

Puppies 4 to 6 Months

By the time puppies reach four to six months of age, they are typically more comfortable in their new home and better able to recognize the rules and boundaries. They’re more independent, and are able to begin more intensive training. While they may still have occasional accidents and bouts of misbehavior, puppies at this age are much easier to train and manage than younger puppies.

Separation anxiety may still be a factor at this age, but it’s typically less severe than it was at younger ages. If your puppy is still exhibiting signs of separation anxiety, it’s important to provide them with a safe and secure environment, as well as to reinforce positive behaviors when they’re left alone.

Puppies 6 Months and Older

By the time a puppy reaches six months of age, they’ve usually grown out of the worst of their mischievous behaviors. They’re more independent and better-behaved, and are able to respond to commands and cues more effectively. Accidents and misbehavior are still possible, but they’re far less likely than at younger ages.

At this age, separation anxiety is usually no longer an issue, as puppies are more comfortable in their home environment. They’re also more able to understand the rules and boundaries of the home, which helps to eliminate behavioral issues.


Puppies can present different levels of difficulty when it comes to training and managing their behavior. The age of the puppy is an important factor to consider, as younger puppies are more likely to act out and display separation anxiety, while older puppies may be better-behaved and more independent. It’s important to take into account the age of a puppy when considering their behavior, as this can help to ensure that they are given the best care possible.

## Common Myths about Puppy Behavior
1. Myth: A puppy will be worst behaved when they reach a certain age.
Fact: While some behaviors may increase in intensity at certain ages, such as teething or rebelliousness during adolescence, there is no definitive age when a puppy will be worst behaved. Every puppy is different and will behave differently depending on their individual personality, experiences, and training.

2. Myth: A puppy will have better behavior if they’re punished.
Fact: Punishment is not an effective way to teach a puppy good behavior. Punishment can cause a puppy to become anxious, fearful, or aggressive, which can lead to further behavioral issues. Positive reinforcement, such as providing treats for desired behaviors, is a much more effective way to train a puppy.

3. Myth: Puppies will naturally outgrow their bad behavior.
Fact: While some behaviors may naturally decrease in intensity as a puppy matures, most bad behaviors will not go away on their own. It is important for owners to be proactive in training their puppy to ensure that bad behaviors do not become ingrained.

Frequently Asked Questions

At what age is a puppy the most difficult?

Puppies typically require the most effort and patience when they are between the ages of 6 and 18 months. During this stage, puppies are often more energetic and will test boundaries. Proper training and socialization can help manage this stage.

How do I stop my puppy from destructive behavior?

Providing your puppy with plenty of exercise and mental stimulation can help reduce destructive behaviors. Keeping your puppy in a safe, pet-proofed area when you are not able to supervise them can also help. Providing them with appropriate toys and chews is also important to redirect their chewing and biting. Training and socialization is also key to helping your puppy learn appropriate behaviors.



Bringing a puppy into your home can be exciting but it requires understanding their age-related behaviors. Young puppies up to 4 months are more difficult to train and may act out by barking, chewing, and nipping. They may also have accidents and separation anxiety. Between 4-6 months, they are more independent and easier to train but may still have occasional misbehavior. After 6 months, they are more able to understand rules and boundaries and separation anxiety is no longer an issue. It’s important to consider a puppy’s age when caring for them.
