Ages & stages
What to train a dog at 3 years
By three, the puppy chaos is usually gone and what is left is the dog you live with. That is good news and a small trap. Many mature dogs coast on what they know, and owners stop asking for precision. This stage is about sharpening, stretching and giving a capable mind enough to do. Ages are approximate; some breeds mature later.

Refine the basics
Polish the cues your dog half knows.
Plenty of adult dogs have cues that work, technically. The sit comes on the third ask, the heel drifts a step wide, the stay breaks when you turn around. Pick one cue at a time and raise the standard: ask once, wait, and reward only the clean version. Short, sharp sessions before a meal often get better effort than long ones.
Then layer the three Ds: duration, distance and distraction. A down that lasts five minutes in the living room is a different skill from a down at the edge of a busy park. Raise only one D per session, and lower the others while you do. If your dog fails twice in a row, the step was too big, not the dog too stubborn.

- Shrink the step after misses
A busy mind
New skills and work for a grown dog.
Mature dogs often pick up new things quickly because the basics are in place. Try scent games, like hiding a treat in one of three boxes, or a trick that uses the body, like backing up or paw targets. Rotate food puzzles and sniff walks through the week. Many dogs given enough mental work tend to settle better at home, though a sudden change in energy, sleep or temper is a reason to see your vet first.
What to leave for later depends less on age now and more on readiness. Skip advanced off-leash work until recall is solid on a long line, and do not treat long-standing fear or reactivity as a weekend project. That calls for a professional assessment; Behaviour Rehab, at $4,850 to $5,760 plus GST after a full assessment, is built for it. For polishing, Advanced Off-Leash works on off-leash heel, distance stays and public manners, and a $150 private session may cover it.
Asked and answered
The questions people ask us.
Can a 3 year old dog still learn new tricks?
Yes. Adult dogs often learn well because they already understand how training works. Keep sessions short, reward generously and pick tricks that suit your dog's body.
Is it too late to train a 3 year old dog?
No. Three is a comfortable age for refining old cues and adding new ones. Long-practised habits may take more patience, and fear or aggression deserve a professional assessment rather than guesswork.
How do you keep an adult dog mentally stimulated?
Mix scent games, food puzzles, sniff-heavy walks and short training sessions on new skills. Variety tends to matter more than length. If your dog seems restless despite that, check with your vet and consider a professional look at the routine.
Should a 3 year old dog go to board and train?
It depends on the goal. Board and train can suit focused projects like off-leash reliability or behaviour work, while refinement often fits private sessions you practise at home. The consultation is where we recommend one, and we name the smaller option when it fits.
