Puppies can look so tiny and fluffy that it is hard to picture the big dog they will become. Some breeds change so much that you might do a double take.
Size, coat, and even posture can transform as they grow. Knowing what is coming helps you pick the right training, grooming, and activities from the start.
Great Dane
Those knobby-kneed pups look like baby giraffes, then they stretch into couch-hogging giants. Early on, teach calm greetings and no jumping, since adult size arrives fast.
Crate training helps curb zoomies during growth spurts and saves fragile furniture.
Provide joint-friendly exercise, thick bedding, and slow-growth large-breed food to protect bones. Short training bursts work best for their sensitive nature and big hearts.

Bearded Collie
Bounce is their middle name as puppies, then they mature into breezy, bearded charmers. Channel the pogo energy with nose-work games and wind-friendly walks.
Teach impulse control at doors and gates for safe greetings during windy days.
Daily detangling under the harness prevents painful knots, especially during weather changes. Use upbeat training with plenty of movement, since they think best while trotting.
