Nobody warns you that the first month with a puppy is mostly about floors.

The good news is that house-training is one of the few parts of dog ownership with a genuine consensus behind it. The Humane Society’s guidance puts the whole process at four to six months, and the ASPCA is refreshingly blunt that “house training is not an exact science — there’s no sure-fire formula or timetable that will work for every dog.”

The routine does most of the work

Take a puppy out at least every two hours, and always after waking up, after playing, and after eating or drinking. The rough guide to bladder capacity is about one hour for every month of age — so a three-month-old may need to go roughly every three hours. Treat that as a ceiling, not a target.

Feed at the same times every day. Puppies usually need to relieve themselves soon after eating, so predictable meals give you predictable trips outside. To cut down on overnight accidents, the Humane Society suggests lifting the water dish about two and a half hours before bedtime.

Supervision, and what to do when you can't

The ASPCA’s advice is to limit the run of the house to one or two rooms where you can see the puppy at all times. When you cannot watch, the Humane Society suggests tethering the puppy to you or to nearby furniture on a six-foot leash, or confining them to a small area.

The crate, done properly

A crate should be large enough for the dog to stand up and turn around in. Puppies under six months should not be crated for more than three or four hours at a time, and a useful ceiling is their age in months plus one hour.

Introduce it slowly: door off or propped open, comfortable bedding, treats scattered in, and let the puppy explore at their own pace. The American Animal Hospital Association is firm on this — a puppy should learn the crate “through positive association, never by forcing them inside or leaving them to cry it out”, and the door should stay open until they choose to rest there.

And the crate is never a punishment. The Humane Society puts it plainly: crates “should never be used for punishment.”

Overnight

Expect to get up. Keep the crate in your bedroom or just outside it at first, so the puppy feels you nearby and you can hear when they need out. AAHA notes that a night crate is not actually compulsory — plenty of households skip it — but if you use one, proximity matters.

Rewards, and accidents

Wait until they have finished before you praise or treat. Puppies will stop midway if you interrupt them, which is how a half-finished job ends up back indoors. Then make a fuss of it.

When there is an accident — and there will be — take the puppy calmly outside, reward them if they finish there, and clean the spot thoroughly so the smell does not invite a repeat.

Do not punish, scold, or rub a nose in anything. The Humane Society says scolding “will only make them fearful”, and the ASPCA points out the simple mechanical problem with telling a dog off after the fact: “a dog will not learn anything by being scolded for a past accident, even one a few minutes old.” You are not teaching them where to go. You are teaching them to hide from you.

When it is a vet visit, not a training problem

If a dog who was house-trained starts having accidents, stop training and call a veterinarian. Cornell’s Riney Canine Health Center lists “accidents in house” among the most common signs of a urinary tract infection, alongside straining to urinate, frequent small amounts, foul-smelling urine, excessive licking and blood in the urine.

A sudden change in a settled dog is information, not disobedience.

This week’s adoptable dog is Milo, who has been waiting since February. And if you are weighing up a puppy against an older dog, Skadi’s listing is a good illustration of what an adult dog tells you up front.
