Bernese Mountain Dogs aren't fully mature until age 2–3. You're living with a puppy brain in an adult body for longer than most breeds are even considered adolescents. The result: a 100-pound dog who doesn't know their own size, has the impulse control of a teenager, and whose growth plates haven't closed yet.
Start Bernese Mountain Dog's training plan →A Bernese Mountain Dog is still in the cognitive equivalent of adolescence at their first birthday, and won't fully settle into their adult temperament until year 2 or 3. Training has to start early — not because Berners are stubborn, but because by the time they're big enough to cause real problems, the behaviors are already practiced.
Bernese growth plates don't fully close until 18–24 months. Hard running, high jumping, repetitive stair climbing, and sustained exercise on pavement during this window can cause hip dysplasia, elbow dysplasia, and ligament damage. The answer: controlled, moderate activity — short walks, gentle play, mental work, swimming.
Bernese Mountain Dogs are calmer than herding breeds, which leads owners to skip training entirely. "He doesn't really need it — he's so mellow." Then the mellow puppy becomes a 100-pound adult who pulls on leash like a freight train and has zero recall because nobody taught it.
I'm Jason. I built FetchCoach because when I got Baelor — my Golden Bernese, now 4 months old — every training app I tried had no memory of where we left off and no concept of breed-specific challenges.
Baelor is a Golden Bernese — so I know this developmental timeline personally. I watched him grow from a clumsy puppy into a powerful young dog who could drag me across a park. FetchCoach tracks your dog's age, breed, and actual skill level to build a plan appropriate for right now — not a generic timeline designed for a breed that matures twice as fast.

FetchCoach is voice coaching — 15-minute sessions, 60 minutes per month. Bernese Mountain Dogs also have breed-specific health considerations (cancer risk, hip/elbow dysplasia) that require veterinary partnership.
Tell us your dog's name, breed, and biggest challenge. Your coaching plan starts from there.
