6 months old: welcome to the teenage phase
Somewhere around the half-year mark, the puppy who came when called, sat at curbs, and gazed at you adoringly will look you dead in the eye, consider your recall word, and go sniff a bush instead. Congratulations. You have a teenager.
Nothing is broken
With my first puppy I genuinely believed I'd ruined the dog. The recall we'd drilled for months evaporated. Known cues got a thoughtful pause and a counteroffer. The crate, beloved for sixteen weeks, became a negotiation. I want to save you the despair I felt: this is adolescence, it is normal, and it is temporary. The brain is rewiring, hormones are arriving (if your pup isn't neutered or spayed yet), and independence is the developmental project of the next few months. The training didn't vanish — it's just temporarily outvoted.
The fix isn't new training; it's old training, patiently maintained. I went back to paying generously for recalls I'd started taking for granted, kept a long line on her in open spaces instead of trusting off-leash optimism, and lowered the difficulty whenever she started failing repeatedly. You can't lose the teenage months, but you can absolutely lose your temper, and only one of those does damage.
The body catches up — and overshoots
A six-month-old has most of its height arriving and a surprising amount of strength, with none of the judgment. Adult teeth are mostly in by now, which ends teething but begins the era of recreational chewing — powerful, contented, destructive-if-unsupplied chewing. The toy budget I'd been winding down went right back up. Meals typically settle toward two a day somewhere around this age (your vet and the food label have the final say, as ever), and many owners are discussing spay/neuter timing with their vet around now — recommendations vary by breed and size, and that's genuinely a vet conversation, not an internet one.
Exercise: more, but still not unlimited
The energy at six months is real, and so is the temptation to fix it with massive runs. Joints are still growing, especially in larger breeds. We scaled walks up gradually and got more mileage — literal and figurative — out of mental work: sniffy walks where she chose the route, food puzzles, ten-minute training games, a flirt pole in the yard. A half hour of brain work flattened her more reliably than an hour of trotting ever did.
From my notebook: the witching-hour zoomies from
week ten made a comeback at six months, bigger and faster. Same playbook: clear the coffee table, enjoy the show.
Keep socializing — quietly
It's tempting to consider socialization "done" because the sixteen-week window closed. I think of adolescence as the maintenance phase: keep new experiences coming at an easy pace, keep paying for calm behavior around skateboards and toddlers and other dogs, and don't cash out the confidence you built in those early weeks. Teenage dogs can get bolshie with other dogs as hormones arrive; I curated her playmates more carefully at six months than I did at twelve weeks.
The part nobody tells you
Adolescence is also when the actual dog shows up — the personality that's going to live with you for the next decade. Maple's particular comedy (the toy she brings to the door, the theatrical sigh when the laptop opens) all emerged in these months. The teenage phase tests you precisely because the dog is becoming someone. It's the best chapter so far. It's just also the most annoying.

Questions I get asked a lot
Why is my 6-month-old puppy suddenly ignoring commands?
Adolescence. The brain is rewiring for independence and your known cues are temporarily outvoted by hormones and novelty. It's normal and it passes. Go back to rewarding the basics generously, use a long line instead of trusting off-leash recall, and don't escalate to anger — the training is still in there.
How much exercise does a 6-month-old puppy need?
More than at four months, but joints are still growing — especially in large breeds — so we scaled up gradually rather than jumping to long runs. Mental work (sniffy walks, food puzzles, short training games) tired mine out more reliably than mileage. Your vet can tailor this to your breed.
Should my puppy be neutered or spayed at 6 months?
This one is genuinely a vet conversation. Recommendations have shifted in recent years and vary by breed, size, and individual health — larger breeds are often advised to wait longer. Ask your vet what current guidance says for your specific dog.
Is my 6-month-old puppy done teething?
Mostly — adult teeth are generally in around this age. What replaces teething is strong recreational chewing, which lasts well into the second year for many dogs. Keep the chew supply stocked; the alternative is your furniture.
