How do I take care of a dog?

How common is this pet? 71 million American households kept a dog in 2025, which is 53 percent of all households.Counted by the American Pet Products Association. APPA 2026 Dog Report, published July 2026

A dog is the most expensive, most time-hungry mainstream pet in America — and for the right household, worth every hour and dollar.

Dogs

A domestic dog is a social carnivore that has lived alongside humans for at least 15,000 years, and the only animal on this list that will actively try to work out what you want. Dogs cost more than most first-time owners expect — food, insurance, preventative vet care and grooming run to a few hundred dollars a month for a medium dog, before anything goes wrong — and they need company. A dog left alone all day is the single most common cause of the behavior problems that get dogs rehomed.

LifespanMedian 10+ years in modern studies; small breeds 10-15+, giant breeds often 8-10
Daily timeMultiple hours of direct and supervisory care, every day
Monthly costRoughly $43-$87 in recurring basics by size; ~$116/month on the full ASPCA budget with insurance
Space neededIndoor living space with the family, plus daily outdoor exercise; a yard is a convenience, not a substitute
Good for beginners?Moderate — trainable and social, but costly and demanding
Good with kids?Often, with supervision — but breed energy and training matter more than species

What you're signing up for

A dog is a 10-to-15-year commitment to another creature's entire daily life. Modern data says lifespans are rising, not falling: every major study using post-1997 data reports a median life expectancy of 10 years or more, up from 8.5-8.6 years in 1980s-era datasets. Banfield Pet Hospital's 2.2-million-dog dataset put the average at 11 years. Size is the dominant predictor — small breeds routinely reach 10-15+ years while giant breeds often live 8-10, because large dogs age faster.

The daily reality is what surprises people. Dogs need exercise, two feedings, training, grooming, and — this is the part buyers skip — companionship. A dog left alone chronically develops separation-related problems; the ASPCA identifies drooling and destruction focused on doors and windows as hallmarks of separation anxiety, not disobedience. Realistically you are signing up for multiple hours of direct and supervisory care per day, every day, for a decade or more.

The thing people most often don't realize until it's too late: breed choice matters more than the decision to get a dog at all. The AKC warns plainly against choosing active breeds without an active lifestyle. A Border Collie in a one-bedroom apartment with a desk-job owner is the classic mismatch, and it ends in destroyed furniture, a frustrated dog, and too often a shelter surrender. Be honest about your energy before you fall for a pair of eyes.

Housing

Dogs live indoors, with the family. That is the welfare baseline, not a preference. A yard helps, but it does not replace walks, training, and engagement — a dog alone in a yard is still an understimulated dog.

Exercise scales with energy level, not size, and this is where most mismatches happen:

Mental exercise is part of the requirement, not a bonus. Sniffing, training sessions, and food puzzles work the dog's brain; scent work in particular taps the dog's dominant sense.

Feeding

Feed a complete-and-balanced commercial diet that meets AAFCO nutrient profiles for your dog's life stage — growth formulas for puppies, adult maintenance for grown dogs. Large-breed puppies specifically need large-breed growth formulas to control calcium and growth rate.

Frequency by life stage:

The mistakes that hurt dogs are boring and common. Free-feeding — leaving food down all day — is often not recommended by veterinarians and drives obesity. So does eyeballing portions: individual metabolism varies by up to 30%, so measure. Cap treats at about 10% of daily calories. Skip raw diets; they carry bacterial and parasitic contamination risks without demonstrated benefit. The scale of the problem is stark: 59% of US dogs are overweight or obese, and 36% of owners of heavy dogs thought their dog's body condition was normal or thin.

Never feed:

If your dog eats any of these, call the ASPCA Animal Poison Control Center at (888) 426-4435.

Health

The conditions insured dogs actually get, per 3.5 million Nationwide claims in 2023, with average treatment cost in the first 30 days: allergic skin disease is number one (410,500 claims, $240), followed by gastroenteritis ($614), ear infections ($280), arthritis ($446), trauma ($629), dental disease ($1,072), urinary tract infections ($499), and valvular heart disease ($565). On top of that, 59% of dogs are overweight or obese, and 80-90% of dogs over age 3 have some degree of periodontal (gum) disease — worse in small breeds.

Early signs owners miss:

Go to a vet today if: your dog has eaten a known toxin; is seizing or loses consciousness; has difficulty breathing; shows blood from the nose, mouth, or rectum, coughs blood, or has bloody urine; has severe bleeding, a fracture, a burn, an eye injury, or a snake bite; shows heatstroke signs (heavy panting, drooling, weakness) or shock (weak pulse, shallow breathing, dazed eyes); is choking; retches without producing anything with a hard, swollen belly and pacing — that is bloat (GDV), minutes matter, and large deep-chested breeds are at highest risk; or is a male straining to urinate and producing nothing.

What it really costs

Setup runs $470 for a small dog, $565 for a medium, $560 for a large by ASPCA Pet Health Insurance estimates — crate or carrier ($40-60), collar and leash ($25-35), a training class (about $110), plus initial medical care. Rover's 2025 report puts the full first year at $1,150-$4,420 including initial vaccines and spay/neuter.

Annual costs, honestly, depend on who's counting. The ASPCA's itemized budget lands at $1,391 a year: food $300, routine medical $225, heartworm/flea/tick preventives $185, toys $37, treats $60, insurance $516, license $15, grooming supplies $28. Recurring basics alone, without insurance, run $512 a year for a small dog, $669 medium, $1,040 large. The AVMA's 2022 survey found dog households averaging $362 a year on veterinary visits, with a typical wellness visit at $192. Accident-and-illness insurance averaged $676 a year (about $56 a month) in 2023 — and veterinary fees rose 11% year over year in Rover's 2025 report, so budget for the trend.

Over a 10-year lifespan, Rover estimates roughly $34,550. The unglamorous truth: the dog is the cheap part. A single dental disease episode averages $1,072; skipping $185 of annual heartworm prevention risks treatment that costs many times more.

Daily and weekly routine

Daily - Exercise matched to breed energy — a walk minimum, real exertion for high-energy breeds - Two measured meals (more for puppies) - Fresh water - Training or mental work: a short session, a food puzzle, or a sniff-heavy walk - Companionship — dogs are not part-time animals

Weekly - Brushing (daily for heavy coats) - Ear check, especially for floppy-eared and allergy-prone dogs - Weight and body-condition check by feel

Monthly - Heartworm, flea, and tick preventives, year-round - Nail trim - Restock food; audit treat spending against the 10%-of-calories cap

Annually: a wellness exam and heartworm test, even when the dog seems fine.

Common mistakes

  1. Budgeting for the $500 setup but not the $1,391 yearly reality or four-figure emergencies. Price the whole decade before you commit.
  2. Skipping annual exams and preventives. Treating illness costs far more than preventing it; heartworm treatment costs many times more than year-round prevention.
  3. Not seeing the fat. 36% of owners of overweight dogs called them normal or thin. Learn body-condition scoring and ask your vet to show you.
  4. Free-feeding and unmeasured portions. Feed scheduled, measured meals.
  5. Choosing a breed that outmatches your energy and time. Match the dog's exercise needs to the life you actually live, not the one you plan to start.
  6. Punishment-based training tools — shock, prong, intimidation. The veterinary behavior profession (AVSAB) links them to increased fear and aggression; use reward-based training for every dog.
  7. Missing the socialization window. It closes around 12-14 weeks; start classes and safe exposure as early as 7-8 weeks with age-appropriate precautions — before full vaccination, not after.
  8. Ignoring teeth until disease is advanced. 80-90% of dogs have periodontal disease by age 3; brushing and dental care are routine care, not extras.

Is this pet right for you?

A good fit if... - You can give hours of attention and activity every single day for 10-15 years - You can absorb roughly $1,400 a year plus four-figure surprise vet bills - Your household's real energy level matches the breed you're choosing - Someone is home enough that the dog isn't routinely alone all day - You want a trainable, deeply social companion and will train with rewards, not force

Think twice if... - You work long hours away from home with no dog care plan - Your budget has no room for insurance or an emergency fund - You want a specific high-energy breed for its looks, not its job - You're a first-time owner drawn to a working or herding breed - You expect a yard to do the exercising for you

Worth knowing

Dogs live in a world of smell. They carry 100+ million olfactory receptors to our roughly 6 million, the smell-analysis area of their brain is proportionally about 40 times larger than ours, and estimates put their sense of smell 1,000-10,000 times better. A sniff-heavy walk is real enrichment, not dawdling.

Fixing your dog is a longevity intervention. In Banfield's 2.2-million-dog dataset, neutered males lived 18% longer and spayed females 23% longer than intact dogs.

Skin, not stomach, is the top vet complaint. Allergic dermatitis was the number-one canine insurance claim with 410,500 claims in a single year.

Most dogs have dental disease before kindergarten age. 80-90% of dogs over 3 have some periodontal disease, and small breeds have it worse.

Dogs are living longer than ever. Studies on post-1997 data consistently report median lifespans of 10+ years, versus 8.5-8.6 years in 1980s data. Better care works.

A grape can hospitalize a dog. The culprit is tartaric acid, which dogs cannot process; the result is kidney injury.

Xylitol is deadlier to dogs than to people. It triggers a massive insulin release in dogs but not humans, and it hides in sugar-free gum and some peanut butters. Check labels before sharing.

Nearly half of US homes have a dog. 45% of households in 2022, up from 38% in 2016 — the most popular pet in the country.
