Why Size Changes the Timeline
Big dogs grow up more slowly than small ones.
A Jack Russell is close to adult by about 12 months, while a Great Dane can stay in the teenage phase until around 2 years old.
Giant breeds also tend to reach their senior years sooner.
That's why the checker asks for adult size as well as age.

The Four Training Stages
- Puppy (up to 6 months): short, happy sessions that build trust, name response, crate comfort and potty habits.
- Adolescent (6 months to adulthood): boundary testing and selective hearing. Skills that work at home often fall apart outside.
- Adult: full focus and impulse control. This is the best time to make skills reliable anywhere.
- Senior: still keen to learn, but with slower bodies and fading senses. Gentle sessions on non-slip floors work best.

Why Session Length Matters
A young puppy's focus runs out in a minute or two. Push past that and they start biting, wandering off or getting silly.
Short sessions that end on a win teach faster than long ones that end in frustration.
As your dog grows, sessions can grow too. Most adults can manage 10 to 15 minutes at a time.
When Normal Isn't Enough
Many training problems are just a phase, but a few deserve a closer look.
A sudden change in an adult or senior dog, like new accidents indoors or forgetting cues they've known for years, can point to pain or a health problem. Book a vet check before you change the training.
If biting comes with a stiff body, growling or a hard stare, work with a qualified, reward-based trainer.
