Navigating the teenage years: Understanding your dogs adolescent phase

Your puppy is not so little anymore and suddenly you might notice behaviours that feel frustrating or confusing. If this sounds familiar, your dog could be entering the adolescent phase, a natural but often challenging time for both dogs and their guardians.

What is the adolescent dog phase?

Adolescence in dogs typically begins around six months and can continue until 18 months, though for larger breeds it may last up to three years. During this time, your dogs brain is undergoing significant development, particularly in areas that affect stress response, emotional regulation and decision making. This can make even simple activities, like meeting new people or other dogs, navigating busy environments or following basic cues feel overwhelming.

Many behaviours you thought you had under control as a puppy chewing, jumping, ignoring requests, pulling on the lead can resurface during adolescence. Research also shows that a high proportion of dogs surrendered to rescue centres are within this age range, highlighting just how challenging this developmental stage can be for guardians.

What’s happening in your dogs brain?

During adolescence, the connection between your dogs brains emotional centre which manages decision making and impulse control, temporarily weaken. This can result in:

  • Increased Impulsiveness and risk taking behaviours
  • Heightened fear responses or sensitivity to stimuli
  • Difficulty coping with everyday experiences such as meeting new dogs greeting people or walking in busy areas.

Understanding that these changes are neurological rather than behavioural “problems” helps guardians respond with patience and empathy instead of frustration.

Changes in behaviour on walks

As dogs move into adolescence their relationship with sniffing and scent communication often changes significantly particularly in males. Hormonal shifts heighten their awareness of scent marks and trigger an instinctive need to investigate and respond, which can make them rushed and can exacerbate pulling on the lead. Guardians often notice their adolescent dog suddenly sniffing and marking constantly or even licking specific spots where other dogs have urinated. This behaviour is not mischief its biology. Sniffing and licking allows dogs to interpret complex information about other dogs identity, health, sex and emotional state. For males its a key part of developing social awareness and confidence but it can also make walks feel frantic with them pulling frequently to gather information.

Female dogs can show similar shifts in sniffing patterns, especially as hormonal cycles begin to regulate. They may become more selective or cautious about other dogs, spend longer investigating scents or show temporary changes in sociability. Just like in males, there behaviours reflect developmental and hormonal transitions, not defiance.

In both sexes, sniffing plays a vital role in emotional regulation. It helps them process their environment, release tension, and feel safe. By allowing time for structured sniffing, caregivers can support calmer, more confident walking experiences, even during this hormonally charged phase.

Supporting your adolescent dog

Relationships between care givers and their dogs can really breakdown in this phase due to lack of understanding and its not unusual for dogs to become unsure and at times defensive in this phase as the care givers mood becomes unpredictable due to the frustration of it all. With the right guidance, patience, and management, you can help your dog navigate adolescence and emerge as a confident, well adjusted adult. Here are some key tips:

  • Keep routines consistent, but flexible enough to accommodate emotional ups and downs
  • Prioritise decompression, quiet sniff walks, enrichment, calm time away form stimulation and even days off from walking can help.
  • Avoid punishment or excessive control this can increase anxiety and frustration
  • Use supportive equipment such as a well fitted harness and longer lead to encourage exploration (not a retractable lead)
  • Focus on connection not control strengthen your relationship through trust based interactions this will make a bigger difference than drilling obedience cues.

Adolescent can feel chaotic, but it is a vital stage of development where your dog learns how to navigate the world. With understanding and gentle guidance, this phase can strengthen your bond and set the foundation for a lifetime of calm confident companionship.

Dog Behaviour, Pain and behaviour

Mediator Dogs: Often vital but misunderstood

In group settings, some dogs naturally fall unto the role of mediator. These are the dogs who step in when arousal runs too high, trying to keep things calmer and safer for everyone. They often look like the “fun police”, breaking up the party.

Sadly, they are often misunderstood. Instead of being recognised for their role, they are seen as disruptive and may even be asked to leave day care or a dog walking group. But what looks like “problem behaviour” can actually be a dog working hard to regulate the group.

What mediator dogs are (and are not)

  • They are not the same as fearful or anxious dogs who hide, snap defensively, or struggle to cope nor those whose subtle signals may have been missed over time and are using growling snapping or biting as a defensive mechanism.
  • They maybe the ones who chase the dog that is chasing the ball, not for the ball but in an attempt to slow the dog down when arousal is running high.
  • They might bark at a dog that hasn’t responded to subtler signals when they have had enough but are otherwise very sociable with dogs.
  • They may break up rough or high speed play by barking, intercepting or chasing the players.
  • They sometimes step in during human to human embraces or energetic contact, barking or wedging themselves between people. Often labelled as “jealousy” it is more likely the dog perceives there is potential conflict arising. Dogs do not embrace the way we do, so a hug can be misread as conflict.

Important to rule out first:

Of course if a dog is acting completely out of character and there has been no build up, it is always important to rule out anything physical. When dogs become less tolerant of certain types of interaction such as other dogs sniffing their back end or approaching their head, its vital to first consider discomfort.

  • Interestingly I am often contacted about these behaviours around the age of 2 or 3, when dogs mature but at this time growth plates have generally closed which can highlight discomfort.
  • Joint pain, impacted anal glands (often linked to gut health), or teeth, or ear pain can be just some of the reasons that a dog may have become more irritable or defensive.
  • These factors need ruling out before we assume the behaviour is purely about group dynamics.

Things to consider if you live with, socialise with or work with groups of dogs

Some dogs who attend group walks with other owners, dog walkers or day care from a young age naturally shift into this role as they mature. It may be a progression of personality to manage conflict or arousal, or it may be that they have tolerated things for a long time and finally reached a tipping point.

Instead of automatically excluding dogs who act this way (depending on the severity of the reaction of course), it can help to pause and ask what they might be communicating:

  • Is the group often becoming overstimulated?
  • Could their “Stress bucket” be full from other factors, like a rushed vehicle journey, lack of proper rest, rushed walks with very little processing?
  • Has this behaviour cropped up with other dogs in the group before?

If a dogs has been labelled as disruptive or you notice these patterns it does not mean they are badly behaved, they may be signalling stress, frustration or simply working hard to regulate the group. Acting as the referee too often can build stress over time and escalate into growling, snapping and lunging.

Is there science behind it?

While “mediator dog” isn’t a scientific label, the concept is supported by ethnological research:

  • Third party intervention (“policing”) has been documented in wolves and primates, where individuals step in to prevent conflict. Some studies suggest domestic dogs do something similar.
  • Play research shows dogs adapt their play signals depending on their partner’s responses, showing awareness of group dynamics.
  • Conflict management is recognised across species, where individuals actively prevent or resolve tension.

Some dogs and their wild relatives, like wolves, have been shown under certain conditions to make up after conflict, comfort each other and get help from a third dog to calm things down, especially if they’re very social.

Of course, many factors can drive behaviour and a full behavioural assessment may be needed to untangle the picture for an individual dog. But by recognising the possible role of mediator dogs, we can better support them, appreciate the work they are doing and create safer, calmer group environments.
