Am I Ready for a Dog? The Honest Checklist

The commitment

“Ten to thirteen years” is the wrong number

The figure quoted in almost every guide understates it. The largest study of the question to date — McMillan and colleagues, Scientific Reports, 2024, built from 584,734 dogs across more than 150 breeds and crossbreeds — reports a median life expectancy of 12.5 years: 12.7 for females, 12.4 for males.

The average is the least interesting part. The spread is enormous, and it is decided by the breed you pick before the dog exists. In the same dataset the longest-lived breeds reach medians of 15.4 and 15.2 years, while the shortest-lived sit at 5.4 and 7.7 years. Labradors land at 13.1, Cocker Spaniels at 13.3.

Two structural findings matter more than any single breed number. Flat-faced dogs live shorter lives — the study reports roughly a 40% higher risk of a shorter lifespan than dogs with typically shaped faces, with the French Bulldog at a median of 9.8 years. And large breeds carry about a 20% higher risk than small ones.

So the breed decision is also a length-of-commitment decision, and a cost decision, and it is made at the point where it feels like a decision about looks. Budget for twelve to fifteen years — and expect the last two of them to be the ones that ask the most of you.

Time

What a dog actually costs you in hours

The “at least an hour a day” rule that circulates online has no single published basis, and treating it as one is how people end up with the wrong dog. Requirements differ by breed, by age, by health and by individual: a retired greyhound and an eighteen-month-old working collie are not on the same schedule, and neither is a twelve-year-old with arthritis.

Puppy time, in particular, is not walk-shaped. It is supervision-shaped — toilet trips through the night and every couple of hours through the day, near-constant watching to intercept the chewing before it becomes a habit, and short frequent training sessions rather than long ones. That phase is measured in months, and it lands whether or not the week cooperates.

Mental work counts. Scentwork in the garden, food puzzles, ten minutes of training, an unhurried walk where the dog is allowed to sniff rather than route-march — for many dogs these tire more reliably than distance does. The under-exercised dog and the under-occupied dog present the same way, and only one of them is fixed by a longer walk.

The honest test is not a good day. It is the flu day, the deadline week, the rain at six in the morning in February, the fortnight in hospital. Name the person who covers you before you need them — and if there is no such person, that is a finding, not a detail.

Money

A budget with the line items filled in

Guides tend to quote a range and leave it there. The ASPCA publishes the actual table, which is more useful, because you can argue with a line item and you cannot argue with a range. Its dog column totals $3,221 for the first year, built from three blocks.

Recurring, $1,391 a year: health insurance $516, food $300, routine medical care $225, preventative medication $185, treats $60, toys $37, grooming supplies $28, licence $15 — plus a single day of boarding at $25. That last line is worth staring at: the published annual total budgets one day of kennel time. Every additional day you travel is money the table does not contain.

One-time setup, $1,030: spay or neuter $300, initial medical care $300, training class and home materials $200, collar, leash and harnesses $60, crate $60, carrier $50, grooming tools $40, microchipping $20.

Special costs, $800: professional grooming $300 and dental $500 — the two that first-time owners most often assume do not apply to them.

The currency and the country do not transfer. The categories do. Take the list, price each row where you actually live, and do it before the dog arrives, not in the week you discover what a dental costs.

What no budget table contains is the emergency, and that is the line that ends adoptions. Decide between insurance and a dedicated savings buffer before you have a dog, because policies exclude pre-existing conditions — the decision is available to you now and much less available the day after it is needed. And plan for the shape of the spend: costs are high in year one, settle in the middle years, then climb again in the senior years, when the diagnostics and the medication arrive together.

The first window

Socialisation has a deadline, and it is early

This is the part the readiness checklists leave out, and it is the one with a clock on it. The American Veterinary Society of Animal Behavior’s position statement on puppy socialisation states that the primary and most important time for socialisation is the first three months of life, and that incomplete or improper socialisation in that period raises the risk of fear, avoidance and aggression later on.

Then it puts a number on the stakes: behavioural issues, not infectious diseases, are the number one cause of death for dogs under three years of age. Not because behaviour is fatal, but because behaviour is why young dogs are given up, and being given up is a dangerous thing to be.

Now do the arithmetic that changes plans. If the puppy comes home at eight weeks, roughly four weeks of the most important window remain — and they fall precisely when the vaccination course is not finished. That collision is the whole problem, and the AVSAB addresses it directly: puppies can start socialisation classes as early as 7 to 8 weeks, with a minimum of one set of vaccines given at least 7 days before the first class and a first deworming, and the society’s position is that this should be the standard of care rather than an exception.

Practically, that means the class is booked and the exposure plan is written before the puppy arrives — surfaces, sounds, hats, umbrellas, vehicles, calm adult dogs, being handled, being left alone for short periods, the vet’s waiting room with nothing bad happening in it. Short, positive, and never flooding a frightened puppy. Ask your own veterinarian what is appropriate locally; disease risk is not identical everywhere, and that is exactly the kind of question a veterinarian who already knows your area should answer.

And the counterpart worth saying out loud: if you adopt an adult dog, this window is behind you. That is frequently a reason to prefer an adult rather than a reason to settle for one.

The second window

How you train is not a matter of taste

The draft advice everyone gives — “find a positive trainer” — is correct, and it is stronger than most people realise, because it is a published professional position rather than a preference.

The AVSAB’s 2021 Humane Dog Training position statement holds that only reward-based methods should be used for all dog training, and that aversive methods — electronic collars, prong collars, choke chains, leash corrections and other physical or psychological punishment — should not be used. The reasons it gives are specific: inhibition of learning, increased fear-related and aggressive behaviour, and injury to animals and to the people handling them. It also notes there is no evidence that aversive methods are more effective than reward-based methods in any context.

Which turns choosing a trainer into two questions rather than a leap of faith. Ask what happens when the dog gets it right, and ask what happens when the dog gets it wrong. If the second answer involves a correction, a “stim”, a “pressure” or a “tap”, keep looking — the vocabulary changes far faster than the equipment does. The AVSAB also publishes a plain-language How to Choose a Trainer handout for owners.

Book the class before the dog arrives. Good classes have waiting lists, and the window in the section above does not.

Choosing

Match the household, not the floor plan

The advice that an energetic breed “won’t be happy in a small apartment” is close to right and points at the wrong variable. Square metres are not what a working breed is asking for; a job is. A collie or a shepherd whose exercise and mental work are genuinely delivered will sleep contentedly in a studio flat, and the same dog left under-occupied will systematically dismantle a house with a garden. The question is not how much space you have. It is how many hours, how reliably, and whether you actually enjoy the kind of dog that asks for them.

So take the inventory honestly, and write it down before you fall in love with a photograph: hours available on an ordinary weekday, appetite for daily training, tolerance for hair and mud and noise, who else lives in the house and what they want, allergies, and what the tenancy agreement says. A dog acquired against a no-pets clause is a dog with an eviction attached.

Puppy or adult. A puppy is a project with a deadline and a great deal of unpredictability: adult size, coat and temperament are estimates. An adult dog arrives with all three already known, frequently house-trained, and past the window in the section above. For a first-time owner with a full calendar, the adult is often the better match — not the consolation prize.

Where the dog comes from. “Avoid puppy mills” is usually offered as an ethical point. It is also a measured one. In a 2013 study in the Journal of the American Veterinary Medical Association, owner-reported behaviour was compared using a standard questionnaire across 413 dogs bought as puppies from pet shops and 5,657 obtained from non-commercial breeders. The pet-shop group showed significantly more aggression toward family members, toward unfamiliar people and toward other dogs; more fear of other dogs and of ordinary life events; and more separation-related problems and house soiling. The commercial supply chain does not just raise welfare questions upstream — it shows up in the animal that comes home.

What a responsible source looks like, concretely: you see the puppy with its mother, in the place it was actually reared; health testing relevant to the breed is shown, not asserted; the breeder asks you more questions than you ask them; nothing is ready to leave before eight weeks; and nobody suggests meeting you in a car park. A shelter or rescue is the other good answer — ask what they know about the dog, and take the foster carer’s report seriously. Somebody who has watched the dog live in a house for six weeks knows more than any guess about its breed.

And if a flat face is on the shortlist, treat the earlier lifespan figures as part of the decision rather than trivia. It is a choice about years, veterinary bills and, in many cases, how comfortably the dog will breathe.

Before the door opens

The week before the dog

Dog-proof, at dog height. Cables secured, cleaning products behind a door that latches, bins out of reach or lidded, and medication stored above counter height rather than on it — over-the-counter medicines and supplements top the poison-control statistics year after year. The food and plant hazards are worth learning before you need them, not during: the household-toxins list covers chocolate, xylitol, grapes and the rest, and the first-minutes guide covers what the poison-control services say to do if something is swallowed anyway.

Build a safe space. A quiet, comfortable spot the dog can retreat to and is never dragged out of, and which is never used as punishment. A crate can be exactly this if it is introduced as a good place and not as a container.

Agree the house rules and write them down. Furniture or not, bed or not, who feeds and when, who walks on which days, one recall word that everyone uses, and one answer on food from the table. Rules that the household disagrees about are how a dog learns to ignore everyone equally.

Sort the paperwork before it is urgent. Many national regulators require dogs to be identified — typically by microchip — and registered, and the European Commission’s rules on the movement of pets set uniform animal-health requirements for taking a dog across an EU border, with rabies among the diseases they target. Requirements differ by country and change; ask a veterinarian what applies where you live, and do it before the holiday, not at the border.

Choose the veterinarian before the first emergency. Register, do a friendly no-treatment visit if the practice allows it, and save the out-of-hours number in your phone. Find a veterinarian is a much better search on a calm Tuesday than at two in the morning.

The first days

The quiet arrival

The instinct is to celebrate. Resist it. For the dog, the first day is a total loss of everything familiar, and a house full of delighted visitors is not a welcome — it is another thing to survive. Keep it calm, keep it small, speak quietly, and let the dog decide when to approach. Withdrawn, flat, sleepy or uninterested in food is normal in the first days and is not a verdict on the match.

Start the routine immediately, because predictability is what makes a strange house legible: feeding at fixed times, toilet trips on a schedule, sleep in the same place, walks at roughly the same hours. Structure does more for a nervous dog in week one than affection does.

Expectations are the thing to manage. The shelter heuristic often quoted — roughly three days to decompress, three weeks to learn the routine, three months to genuinely settle — is a rule of thumb rather than a measured curve, and individual dogs vary widely around it. Its value is that it points in the right direction: slower and longer than you think.

Accidents and chewing in this period are development and stress, not defiance. Interrupt, redirect, clean thoroughly with an enzymatic cleaner so the spot does not advertise itself, and adjust the schedule rather than the dog. And book the first veterinary appointment early — a health check, a parasite plan, a look at vaccination status, and the socialisation conversation while it still has time to matter.

Not yet

When the honest answer is “not this year”

Every checklist like this one implies a pass. It also has a failing grade, and almost nobody writes it down: a tenancy with a no-pets clause, a job in flux, a move on the horizon, a baby due, a budget with no room for an $800 line you did not plan. A dog is twelve years. A difficult year is one. Postponing costs you a year of something you want; getting it wrong costs an animal its home.

The useful thing is that the waiting has excellent versions. Foster for a rescue — most cover food and veterinary costs, and you will learn more about your own capacity in six weeks than in six months of reading. Walk dogs at a shelter. Look after a friend’s dog for a fortnight, including the bad-weather mornings. Any of the three will answer the question this article can only frame.

Deciding to wait, and deciding well, are the same decision. Both of them are what a good owner looks like before the dog arrives.

The source

Why the source of your answer matters here

Every number in this article is attached to the document it came from, and you can open each one. That is deliberate, because this subject is saturated with confident figures that nobody can trace — the “hour a day”, the lifespan that is a decade out of date, the cost range that quietly mixes the first year with every year after it.

Lares Pecoris is built on the same rule for veterinary questions: answers come from official product documents and verified veterinary sources, every statement arrives with the document behind it, and when the information is not in a real document it says so instead of guessing.

That is a reference, and a good one to think with. It is not a substitute for the veterinarian who will examine your actual dog — and, in this particular decision, it is not a substitute for meeting the animal.

Questions owners ask

Frequently asked questions

How long does a dog live?

The largest published dataset — 584,734 dogs across more than 150 breeds — puts the median life expectancy at 12.5 years, with females at 12.7 and males at 12.4. The spread between breeds is far wider than that average suggests: the longest-lived breed in the study reached a median of 15.4 years, the shortest-lived 5.4 years. Plan for twelve to fifteen years, and check the figure for the specific breed before you choose it.

How much does the first year with a dog cost?

The ASPCA’s published budget totals $3,221 for a dog’s first year: $1,391 of annual costs, $1,030 of one-time setup costs, and $800 of special costs (professional grooming and dental). The currency and the country do not transfer, but the line items do — price each of them locally before the dog arrives rather than after.

Should a first-time owner get a puppy or an adult dog?

A puppy is a project with a deadline: the veterinary behaviour sources place the most important socialisation period in the first three months of life, which means the work is intensive and time-limited. An adult dog arrives with adult size, coat, temperament and often house-training already known, and that window is behind them. For a first-time owner with a full calendar, the adult dog is frequently the better match, not the compromise.

When should puppy socialisation start, and is it safe before full vaccination?

The American Veterinary Society of Animal Behavior states that the primary and most important time for puppy socialisation is the first three months of life, and that puppies can start socialisation classes as early as 7 to 8 weeks with a minimum of one set of vaccines at least 7 days before the first class plus a first deworming. Its position is that this should be the standard of care, because behavioural issues — not infectious disease — are the leading cause of death for dogs under three years of age. Ask your own veterinarian what is appropriate for your area and your puppy.

Are shock, prong or choke collars ever appropriate?

The AVSAB’s 2021 Humane Dog Training position statement says aversive methods — including electronic collars, prong collars, choke chains and leash corrections — should not be used, citing inhibited learning, increased fear-related and aggressive behaviour, and risk of injury, and noting there is no evidence that aversive methods are more effective than reward-based ones in any context. This is a published professional position, not a matter of training style.

How long does it take a rescue dog to settle in?

Longer than most people expect, and it varies enormously between individuals. The widely repeated shelter heuristic — roughly three days to decompress, three weeks to learn the routine, three months to genuinely settle — is a rule of thumb rather than a measured curve, but it is useful precisely because it sets expectations low and long. Withdrawn, sleepy or unresponsive behaviour in the first days is normal.

Is a small flat a reason not to get a dog?

Floor area is rarely the deciding variable; delivered exercise and mental work are. A working breed whose needs are actually met will settle in a small flat, while the same dog left under-worked will be destructive in a house with a garden. The honest question is not how many square metres you have but how many hours, and how reliably, you can give.

The takeaway

In short

Twelve and a half years is the median, not the ceiling. The first year has a real number attached and the emergency does not. The socialisation window closes at around three months and the training question already has a published answer. Everything else — the bed, the bowls, the breed you like the look of — is the easy part, and it is the part most people plan first.
