Has your well-trained puppy suddenly started ignoring you? Welcome to adolescence. Here's what's really happening between six and eighteen months — and how to come out the other side with your training intact.
Surviving the Teenage Dog: A UK Owner's Guide to Adolescence
If your once-obedient puppy has suddenly started ignoring your recall, testing boundaries, and reacting to things that never bothered them before — don't panic. You haven't done anything wrong. You've simply met the adolescent dog.
Adolescence in dogs typically runs from around six months to eighteen months of age, and it is one of the most misunderstood stages of development. Owners often tell us their dog has "forgotten everything" or "become stubborn". In truth, your dog's brain is undergoing significant change — and understanding what's happening is the first step to getting through it together.
What's Actually Going On
During adolescence, your dog's brain goes through a period of reorganisation. Parts of the nervous system mature at different rates, which can temporarily affect impulse control, focus, and emotional regulation. Combine that with hormonal changes, increasing confidence, and a growing interest in the wider world, and you get the classic teenage profile: easily distracted, quick to test limits, and far more interested in the environment than in you.
Recall is usually the first casualty. The puppy who once galloped back at the sound of their name discovers that other dogs, wildlife, and interesting smells are now far more compelling. This isn't disobedience — it's a developmental phase that rewards owners who adjust their training rather than abandon it.
The Three Golden Rules for the Teenage Months
1. Don't stop training — change your training.
Short, frequent sessions beat long, frustrating ones. If your adolescent dog struggles to focus for ten minutes, work in two-minute bursts throughout the day. Raise your rate of reinforcement: pay generously for every good choice, because attention is now harder to earn and easier to lose.
2. Rebuild your foundations on lead first.
If recall is wobbling, take a step back. Practise name recognition and check-ins on a long line in low-distraction environments before graduating to busier parks. Never test a recall you're not confident of — every failed attempt teaches your dog that ignoring you is possible.
3. Manage the environment, don't just train the dog.
Adolescence is the wrong time to rely on willpower alone. Use management tools — leads, gates, long lines, baby gates — to prevent your dog rehearsing behaviour you don't want. Every time your dog practices ignoring you, that habit gets stronger. Make the right choice easy and the wrong choice difficult.
Common Challenges and Sensible Responses
Selective hearing. If your dog only listens when food is visible, your reward history needs rebuilding. Practise paying for attention when your dog doesn't expect it, and keep rewards varied — food, play, and genuine praise all have a place.
Destructive behaviour. A teenage dog with too little physical exercise and mental stimulation will find their own entertainment. Increase enrichment: scatter feeding, puzzle toys, chews, and sniffing walks all burn energy without ramping your dog into an over-aroused state.
New fears or reactivity. Some dogs become more sensitive during adolescence. If your dog develops new worries — barking at things they previously ignored, for example — don't force them to "face it". Create distance, reward calm behaviour, and seek help early. Adolescence is a common window for reactivity to emerge, and early, kind intervention makes a real difference.
The Light at the End of the Lead
Here's the encouraging part: adolescence ends. Most dogs begin to settle somewhere between eighteen months and two years, and the dogs who come out the other side well are the ones whose owners kept training consistently, kindly, and with realistic expectations through the hard months.
If you're struggling, you're not alone — and you don't have to muddle through. Our board & train programmes and 1-2-1 coaching sessions are built around exactly this stage, giving you a clear plan, practical techniques, and support from trainers who work with adolescent dogs every single day.
The teenage phase is temporary. The relationship you build through it is permanent.
