What's actually happening
During adolescence your dog's brain is remodelling, the emotional and impulsive systems running ahead of the calmer, decision-making parts. Add hormonal changes and a natural drive to explore the wider world, and you get a dog that is more distractible, more reactive to novelty, and less inclined to check in with you. It genuinely finds it harder to control impulses right now , this is biology, not attitude.

Don't take it personally , or give up
The biggest mistake owners make is concluding that training "failed" and either stopping or getting tougher. Both backfire. Harsh punishment during a sensitive, sometimes fearful stage can damage your relationship and create lasting problems, while giving up lets bad habits set in. What your teenage dog needs is calm, consistent leadership and a lot of patience , the work you put in now is exactly what carries through to adulthood.

Reward every choice to reconnect. Adolescence is when consistency quietly pays off.
Keep training alive and manage the environment
Don't abandon cues just because they seem shaky , keep practising known behaviours, reward generously, and quietly raise your rate of reinforcement. At the same time, manage the environment so your dog can't rehearse bad choices: use a long line for a wobbly recall rather than risking off-lead failures, keep tempting items out of reach, and set your dog up to succeed. Prevention beats correction throughout this phase.

Meet the need for stimulation
Much teenage "naughtiness" is under-met physical and mental needs colliding with a body full of energy. Give real outlets: sniffy walks, chews, food puzzles, scent games, and short training bursts that make your dog think. In small flats and hot, humid climates, mental enrichment is a practical way to tire a dog when long midday walks aren't sensible , a fifteen-minute puzzle can settle a dog better than a forced march.

Channel teenage energy into legal outlets , sniffing, chewing, and puzzles beat boredom-driven chaos.
Handle fear periods and know when to get help
Some adolescents go through a "second fear period" where previously fine things suddenly worry them. Don't force your dog toward the scary thing or flood it; add distance, stay upbeat, and let it recover , these wobbles usually pass. Keep routines predictable, and remember this stage is finite. If behaviour is escalating rather than settling, that's your cue to get tailored support.
