Puppy adolescence surprises owners mostly because nobody warns them it is coming. The puppy who recalled beautifully, walked politely, and settled on cue starts, somewhere in the second half of the first year, to blow off known commands, discover the opposite sex and rival dogs, pull towards every distraction, and treat your voice as an optional podcast. This is not spite and it is not your early training failing — it is a brain under hormonal reconstruction, and the job is to maintain the training through it rather than mourn it.
Recognise what adolescence is actually doing
A teenage puppy's priorities genuinely reorder. Social information — other dogs, scent marks, wildlife — becomes neurologically louder at exactly the moment impulse control is at its wobbliest, which is why a cue the puppy 'knows perfectly well' evaporates beside a football game and reappears in your kitchen. Understanding this changes your strategy: the puppy is not choosing defiance, so confrontation achieves nothing, while management and rehearsal in easier settings achieve a great deal. Expect the phase to last months rather than weeks, to affect different skills at different times, and to include odd regressions in housetraining, confidence, or sleep that resolve as maturity arrives.
Go back to basics without starting over
The practical response is to make training easier, not harsher. Shorten sessions to a few minutes, raise the value of rewards back to the high level you used with a baby puppy, and rehearse known cues in boring places before asking for them anywhere exciting. Put recall back on a long line in open spaces so your teenager cannot practise the self-rewarding lesson that ignoring you produces a brilliant chase; every successful repetition of that lesson makes the phase longer. Revisit the foundation exercises — name response, hand touch, recall games between two people, settle on a mat — and pay for them like new behaviours. Owners often find the revisited basics come back far faster than they were first learned, because the knowledge is in there; adolescence is scrambling access to it, not deleting it.
Hold the routine steady while everything else wobbles
Teenage puppies test boundaries partly because boundaries are interesting, so this is the worst moment to let rules drift. If the puppy was not allowed to jump at visitors, mug food from plates, or drag you to other dogs before, those rules stay, enforced by management — leads, gates, food put away — rather than by repeated shouting the puppy has learned to tune out. Keep sleep generous too; adolescent dogs still need a great deal of rest, and the evening mania owners dread often belongs to an overtired teenager. Predictable meals, walks, training, and downtime give a hormonally chaotic puppy an external structure to lean on while the internal one is rebuilt.
Use the teenage energy instead of fighting it
Adolescence brings real gifts alongside the chaos: stamina for longer adventures, the focus for more complex training in short bursts, and a growing interest in games with you. Channel the new drive into activities with rules built in — search games, trick training, controlled play, and sniffy decompression walks where the puppy may investigate the world at length on a long line. These outlets drain exactly the restlessness that otherwise fuels door-dashing, lead lunging, and garden fence-running. Choose environments honestly during this phase: the busy dog park that was fine for your social puppy may over-face or over-arouse your teenager, and quieter walking with one known companion often serves training far better.
Consistency across handlers decides whether the maintenance plan survives contact with real life, because a teenager only needs one person who lets recall slide. KinsLe's Care Teams lets you assign the day's short training, long-line walk, and settle practice to whoever is handling your puppy, with each completed task marked by a timestamp, so the adolescent plan is followed by the whole household.
