The 3 Secrets of Canine Adolescence

Between five months and three years of age, more dogs are surrendered to shelters than at any other life stage.

❌ Not puppies.

❌ Not seniors.

Adolescents.

These are the dogs whose guardians did everything right, socialisation classes, reward-based training, a careful breeder, and then watched it all seem to unravel around the seven-month mark.

The recall fell apart.

The reactivity arrived from nowhere.

The dog they knew became a dog they didn't recognise.

And the advice they're given is almost always wrong.

  • "He'll grow out of it."

  • "She just needs more exercise."

  • "Get him neutered, that'll calm him down."

  • "You need to be firmer."

None of it reflects what's actually happening inside the adolescent dog.

And as a professional, you already know that, because you're the one being called in when the standard advice has made things worse.

This Masterclass is for you.

WHAT THIS MASTERCLASS IS

A 60 minute live session unpacking three things about canine adolescence that the wider industry has either misunderstood, oversimplified, or ignored entirely.

Not tips. Not techniques.

The underlying science that explains why adolescent dogs behave the way they do, why so much standard advice fails them, and what genuinely changes outcomes during this developmental window.

You'll leave with a clearer professional framework for assessing adolescent cases, language to use with guardians who are at the end of their tether, and a sharper understanding of where the real intervention points are.

WHO THIS IS FOR

DOG TRAINERS

BEHAVIOURISTS

BEHAVIOUR CONSULTANTS

DAY CARE MANAGERS

WALKERS

RESCUE STAFF

VETERINARY PROFESSIONAL WHO WORK WITH DOGS IN THE 3 YEAR TO 5-MONTH WINDOW AND WANT TO OPERATE FROM A STRONGER EVIDENCE BASE

ALSO WELCOME:

Serious guardians who are studying their way through their own dog's adolescence and want professional-level understanding rather than another set of tips.If you're looking for a five-step recall fix or a quick way to "sort out" a teenage dog, this isn't the right room. Everything in the Masterclass is from a welfare-led, force-free, cognitive-led practice.
