Puppy & Young Dog
Adolescent dogs: keep training workable
As your puppy develops, the world may become more interesting and familiar skills less reliable. Adjust management and criteria; changing responsiveness does not establish deliberate stubbornness.
Is my puppy being naughty or anxious?
Retreating to a bedroom, bed or willingly used crate can be healthy coping. After confrontation, a dog may be seeking safety rather than showing stubbornness. Leave the route clear and do not drag, corner or force them out of a safe space.
Make the next attempt easier
Pause the demand, reduce noise and pressure, then invite rather than compel interaction. Reward voluntary approaches and easy familiar responses. Practise in a quiet setting with a clear cue and something the dog values; add distractions gradually. A cue learned at home may not yet work in a busy place. Repeating it louder does not teach that missing step.
Consider context and health
Adolescent confidence, fatigue, distraction, previous rewards and different carers’ cues can change responsiveness. None proves deliberate defiance. Pain or illness can also cause hiding and reduced engagement. Seek a veterinary check for sudden change, persistent withdrawal, appetite or movement changes, or repeated fear. For panic, guarding or significant aggression, manage safety and ask for referral to a qualified, reward-based clinical animal behaviourist; do not wait for adolescence to pass.

What you may notice
Interest in dogs, people, scents and exploration can increase. Recall may seem worse, confidence may fluctuate and frustration may be more apparent. Physical strength can rise faster than skills. Timing and intensity vary with breed and individual development.
Do not attribute every change to adolescence. Pain, sensory changes, illness or a frightening experience can also change behaviour, particularly where the change is sudden or severe.
A practical reset
- Use a lead, appropriate long line or secure area where current recall is unreliable.
- Lower the difficulty: shorter distance, quieter settings and fewer competing demands.
- Reward check-ins and successful returns generously. Avoid endlessly repeating cues.
- Meet needs through a balanced routine of suitable activity, learning, rest and social contact.
- Practise one skill at a time and agree consistent expectations across carers.
- Add a mild challenge only when the easier version is comfortable again.
Revisit recall, lead walking and comfortable separations rather than abandoning reward-based teaching.
Handle new fears thoughtfully
Give more space from a newly worrying object, person or location. Pair manageable observation with something valued and allow retreat. Do not force a greeting to prove there is nothing to fear.
Avoid high-intensity social environments when they overwhelm the dog. Repeated barking or lunging needs management and an individual assessment if persistent. Confidence guidance offers a smaller-step method.
Reproductive development and health
Discuss reproductive changes, season management where relevant and individual neutering decisions with your vet. Neutering is not a guaranteed solution to recall, fear or every behaviour problem. Use the existing neutering decision guide.
Continue vaccination, parasite, dental and growth reviews. A stronger young dog still needs a development-appropriate activity plan rather than adult endurance assumptions.
If the reset doesn’t help
If the dog works at home but struggles outside, lower environmental difficulty further. If the household is overwhelmed, choose essential safety and care priorities rather than adding more exercises. Take turns, arrange support and keep realistic records of progress.
New aggression, guarding, panic, injury or significant changes in appetite, sleep or movement warrant veterinary advice and appropriate behavioural referral. Positive training remains useful, but complex difficulty may need individual help.
Your location matters
Training principles are shared; vaccination exposure, professional services and legal duties depend on location. Any UK-specific rule or register is labelled as UK guidance. Follow local veterinary and public-authority advice.
