Straight answer
When should puppies start potty training?
There is no age at which a puppy becomes ready for potty training, because potty training is not something the puppy does. It is something you do: crate, schedule, supervision, reward, repeat. The puppy simply learns whichever surface it gets to use most. Start managing on the first afternoon and the bladder catches up with the habit a few months later.

Day one plan
The first afternoon home sets the pattern for months.
Before the puppy arrives, decide where it will sleep, where it will pee and who is taking it out. Then run the schedule from the first hour: out after waking, out after eating, out after play, out after every trip out of the crate. Walk to the same spot, stand still, say nothing until the puppy goes, then mark it and pay with a treat right there on the grass, not back at the door.
Between trips, the puppy is either in the crate, on a leash attached to you, or in a small gated area with your eyes on it. Freedom is earned in rooms, one at a time, after a dry week. Accidents are information, not disobedience: they tell you the interval was too long or the supervision slipped. Clean with an enzyme cleaner and shorten the gap. Expect real reliability between four and six months, sooner for some puppies, later for others.
- Out after sleep, food, play
- Same spot every time
- Reward on the grass
- Crate or leash between trips
Calgary winter
The winter puppy needs a shovelled spot and a shorter clock.
A puppy that comes home in December meets a different problem: a yard under snow, a doorstep that is dark at both ends of the day, and cold that makes a small puppy freeze up rather than squat. Shovel a patch of grass or lay down straw the day before the puppy arrives so there is a scent spot that does not change. Carry the puppy to it for the first trips so the whole outing is not spent picking through drifts.
Keep winter trips short and businesslike: coat on, out to the spot, mark, treat, back inside. Do not turn the potty trip into a walk, because a cold puppy learns to hold it until it is back in the warm house, which is the opposite of what you want. Wipe salt and gravel off paws after sidewalk trips. If the deep cold has your puppy refusing to go, a covered spot near the door beats a litter tray in the kitchen.

Asked and answered
The questions people ask us.
When should puppies start potty training?
The day they come home. Set up the crate, pick the outdoor spot and run the schedule from the first hour, because the puppy is forming a surface preference whether you are training or not. Waiting for an older age just means more indoor habit to undo.
What age can you potty train a puppy?
Any age the puppy is in your house. The management side starts immediately; the physical side, holding it for hours, develops on its own between roughly four and six months. Your job is to make sure the habit is fully outdoors by the time the bladder can keep up.
When do puppies learn to go outside on their own?
Puppies do not decide to go outside; they go where they have been rewarded for going. After a few weeks of consistent trips to one spot, you will start seeing the puppy head for the door or fuss when it needs out. Reward that signal the moment you see it.
Puppy potty training age: is five months too late?
No, a five-month-old who still has accidents has an unfinished habit, not a broken one. Go back to the day-one plan, crate and leash between trips, and tighten the schedule. If you would rather hand the reset to us, Puppy Fundamentals builds crate comfort, including nights, and a structured routine, which is the backbone of house training.
