Moving from adolescence into adulthood
There isn’t a precise age at which every dog becomes an adult. Physical and emotional maturity develop gradually rather than arriving on a particular birthday, and the timing varies between individual dogs and breeds.
As dogs move beyond adolescence, we generally begin to see greater emotional regulation and impulse control. The dog who previously found every smell, dog or movement impossible to resist may become more thoughtful and settled. Family routines are familiar, communication between dog and owner has usually developed and everyday life can begin to feel much easier.
Maturity doesn’t mean learning stops. Dogs continue learning throughout their lives, and the behaviours and routines they practise become increasingly familiar. Adulthood isn’t the time to put everything you’ve taught your dog away. Training can simply become much more naturally woven into everyday life.
Becoming more socially selective
This is one of the changes that can really worry owners. A puppy who enthusiastically greeted every dog may become an adult who walks past most dogs without showing any interest in meeting them. Some dogs develop a small circle of canine friends while becoming much less interested in unfamiliar dogs.
Owners sometimes interpret this as their dog becoming antisocial, when very often they are simply becoming more socially selective. We don’t expect adult humans to want to interact with every person they pass in the street, yet we frequently place that expectation on dogs.
There is nothing wrong with a dog who would rather sniff along a hedgerow with you than greet an unfamiliar dog. In fact, being able to peacefully share an environment with another dog without needing to interact with them is an incredibly useful skill. Respecting your dog’s changing social preferences can make walks much more enjoyable for everyone. Not every dog needs to be their friend.
Exercise is only part of the picture
Regular physical activity is important, but exercise alone doesn’t necessarily create a fulfilled dog. This becomes particularly relevant with energetic dogs. When a dog doesn’t settle, one of our first instincts can be to increase their exercise, so the walk gets longer and then longer again. Eventually we can end up with an incredibly fit dog who still doesn’t know how to switch off.
Walking should give dogs opportunities to sniff, investigate and explore as well as move their bodies. Some days that might involve covering several miles together. On another day, your dog may gain far more from slowly investigating an interesting woodland or spending half an hour following scents.
I don’t judge the quality of a dog’s walk by the distance covered. What matters is what the dog got from it.
Enrichment throughout adulthood
Absolutely. Mental stimulation shouldn’t disappear once your dog knows the basics. Scent work, searching for food, problem-solving activities, appropriate play, chewing, exploring new places and learning new skills all give dogs opportunities to use their brains and engage in natural behaviours.
Enrichment doesn’t need to mean constantly buying puzzle toys either. Allowing your dog to investigate an interesting scent can be enrichment. Giving them some choice about which direction you walk can be enrichment. Searching for scattered food in the garden can be enrichment, and sometimes it is simply doing something enjoyable with you.
I particularly love scent work because it allows dogs to use the sense through which they understand so much of their world. It can be adapted for different dogs and abilities and provides meaningful mental activity without us having to continually increase physical exercise. Find out more about scent work classes here.
The important thing is variety and, most importantly, whether your dog actually enjoys it. Something isn’t enriching simply because we’ve labelled it enrichment.
Training throughout adulthood
Yes, although it doesn’t need to resemble a formal training session. One of the myths around dog training is that once a behaviour has been learnt, it is permanently stored away ready to be produced whenever we ask. In reality, skills benefit from continuing to be used and reinforced.
I often think of them like muscles. If we continue using them, they stay strong. If we neglect them for long enough, they can weaken. That doesn’t mean spending hours every week on formal training. Recall can be reinforced during walks, settling can be practised while you’re having a coffee and lead skills happen naturally whenever you’re walking together.
There is also no reason to stop teaching completely new things. Learning doesn’t have an expiry date, and for many dogs learning something new is an enjoyable activity in its own right.
Why choice matters to adult dogs
One thing I would add to the way we traditionally think about adult dog welfare is choice. Our dogs live almost entirely within a world controlled by humans. We decide when they eat, when they walk, where they go, who enters their home and often what they are allowed to investigate. Some of that control is obviously necessary to keep them safe, but within those boundaries there are plenty of opportunities to give dogs a voice.
Which path would they like to take? Would they prefer to greet someone or keep their distance? Which toy would they like? Do they want to continue an interaction or move away? These may seem like insignificant decisions to us, but having some control over what happens to them can be an important part of emotional wellbeing.
A fulfilled life involves more than making sure all of a dog’s physical needs have been provided for. Where it is safe and appropriate, I want the dog to have some say in it too.
Nutrition and maintaining a healthy adult dog
Adult dogs need a complete, balanced diet appropriate to their individual needs, and maintaining a healthy body condition becomes particularly important as the years progress. I’m also qualified in canine health and nutrition, so diet and body condition are things I consider alongside behaviour and lifestyle when looking at the whole dog.
Weight gain can creep up remarkably gradually. A little extra food, fewer opportunities for activity or simply continuing to feed the same amount when a dog’s energy requirements have changed can all contribute. This is why I prefer to look at body condition as well as the number on the scales. You should generally be able to feel your dog’s ribs without pressing through a thick covering of fat, see a waist when looking from above and an abdominal tuck from the side.
Nutrition also has a wider relationship with health, including the gut microbiome. Research into the relationship between the gut and behaviour is developing rapidly and is fascinating, but I think it’s important that we don’t get ahead of the evidence. A healthy diet supports the whole dog, but I wouldn’t present nutrition as a magic solution for behavioural problems.
Behaviour changes in adult dogs are worth noticing
One of the advantages of adulthood is that we usually know our dogs incredibly well, and that makes changes worth noticing. If a dog who normally loves walking suddenly starts hanging back, a dog who has always enjoyed being touched becomes less tolerant of handling, or a previously sociable dog becomes unexpectedly irritable, I don’t assume they’ve suddenly decided to be difficult.
Pain and illness can influence behaviour, sometimes long before we notice obvious physical symptoms. Behaviour can also change because something has happened in the dog’s environment or because their emotional experience has changed. The important thing is not to dismiss it. Check out behaviour support here.
When a familiar adult dog starts behaving differently, ask what has changed. If there isn’t an obvious explanation or the change persists, a veterinary check is a sensible place to start.
One thing I would encourage every adult dog owner to do
Every so often, forget about what your dog can do and think about what they actually enjoy. What makes them come alive?
Perhaps it’s running through woodland. Maybe it’s following a scent, playing tug with you, digging, swimming, lying in the sunshine or spending ten minutes investigating one particularly fascinating lamp post. Sometimes we become so focused on providing what dogs need that we forget to notice what gives the individual dog in front of us genuine pleasure.
Adulthood gives us years to really get to know that dog. Use them.
Frequently asked questions
My adult dog sleeps a lot during the day. Is that normal?
Adult dogs naturally spend a significant proportion of the day sleeping and resting, so plenty of downtime isn’t necessarily something to worry about. What matters is what is normal for your individual dog. A noticeable change in sleeping patterns, particularly alongside changes in appetite, behaviour or willingness to exercise, is worth discussing with your vet.
Is it too late to change an adult dog’s behaviour?
No. Dogs remain capable of learning throughout life. Long-established behaviours may take longer to change because they have been practised repeatedly, but adulthood certainly doesn’t mean learning has finished. If there are everyday skills you’d like to revisit or something new you’d like to teach, you can find out more about my dog training options here.
My adult dog doesn’t play very much. Should I be worried?
Not every dog expresses enjoyment through play, and preferences can change with maturity. Look at your individual dog rather than comparing them with others. However, if a dog who previously loved playing suddenly loses interest, particularly alongside other behavioural or physical changes, it is worth considering whether pain or illness could be involved.
Should adult dogs have rest days from long walks?
There is nothing wrong with having quieter days. Dogs don’t need to complete a prescribed mileage every day to be well cared for. A gentler sniffing walk, some scent work or simply a quieter day can all form part of a balanced life, particularly after an unusually active or stimulating day.
Can an adult dog learn scent work if they’ve never done it before?
Absolutely. Dogs don’t need previous training experience to begin using their nose in structured scent activities. Scent work can be adapted to suit individual dogs and doesn’t require exceptional obedience or athletic ability, which is one of the reasons I enjoy introducing owners and dogs to it.
If you’d like to try it with your own dog, you can find out more about my scent work training here.
Helping your adult dog thrive
It is easy to think of adulthood as the stage where nothing much changes. In reality, these years are incredibly important. They give us the opportunity to maintain physical health, continue supporting emotional wellbeing and enjoy the relationship we’ve spent puppyhood and adolescence building. What we do during these years also helps create the foundations for healthy ageing.
Keep exploring together and keep learning together. Respect your dog’s changing preferences and pay attention to the things that bring them genuine enjoyment. Training can continue to be part of the life you share, but so can doing absolutely nothing together occasionally.
The goal isn’t simply to have a well-behaved adult dog. It is to know the individual in front of you well enough to give them a life they genuinely enjoy, because adulthood isn’t just the long stretch between adolescence and old age. For many dogs, these are the best years of all.
