By the numbers

Dogs in American homes, walks, loneliness and safety.

Dogs at home

~38%of U.S. households have one or more dogs, the CDC estimates.
~2.8Mdogs entered U.S. shelters and rescues in 2025, and about 2 million were adopted.
$3,221estimated first-year cost of a dog, including set-up (ASPCA, 2021 figures).

Research

~20 minmore walking a day, on average, for dog owners than for people without dogs.
71people took part in a small trial in Australia. New dog owners felt less lonely within 3 months.
24%lower risk of death from any cause was linked to dog ownership in a review of 10 studies (3.8 million people). It’s a link, not proof.

Safety

1 in 5people bitten by a dog need medical attention.
~60%of dog owners walk their dog at all, a review of 31 key studies estimated.
5–6is the age when children are usually ready to help care for a pet, pediatricians say.

Why dogs and people bond

Shared gazes, daily care and a family-like connection.

Dogs have lived alongside people for thousands of years. Many owners describe their dog as family, and doctors note that a dog’s daily need for food and care creates a family-like bond.

👀 The power of a shared gazeLooking into your dog’s eyes may boost a bonding hormone in both of you.
Read more

A 2015 study in Japan found that when dogs and owners gazed at each other for a long time, levels of oxytocin, a hormone linked to bonding, rose in both. This did not happen with wolves raised by people.

Other scientists have pointed out limits in the study, and say more research is needed. But it fits what many owners feel: that quiet moments with a dog can feel deeply connecting.

🤲 “You take care of the dog, and the dog takes care of you”Caring for a dog can give life purpose and shape.
Read more

A Harvard Health article quotes a doctor describing dog care as a two-way street: you care for the dog, and the dog cares for you.

In research on people living with mental health conditions, owners said the daily care their pets needed gave them structure, purpose and hope.

🫶 Comfort without judgmentA dog doesn’t care about your bad hair day or your hard week.
Read more

People in research described their pets as giving comfort, affection and acceptance without judgment. Some said they could confide in their pet when it was hard to talk to people.

Petting a dog has been linked to lower stress hormones, and time with animals to lower blood pressure.

For playful lessons dogs can teach us (joy in small things, play, rest after effort), see “Lessons from animals”.

What the research honestly says

Promising signs for loneliness and activity, but a dog is not a cure.

Dogs are the most studied pets, and the research is encouraging in some areas. But most studies show links, not causes, and results overall are mixed.

🫂 LonelinessA small trial found new dog owners felt less lonely.
Read more

In a 2019 Australian study of 71 people, those who got a dog felt less lonely within three months, and still did at eight months, compared with people who didn’t. There were some signs of less negative mood too.

Getting a dog did not change overall psychological distress in this study. The researchers said larger trials are needed.

❤️ Heart health and long lifeDog owners tend to live longer, but healthier people may simply own dogs.
Read more

A 2019 review of 10 studies with about 3.8 million people found dog ownership was linked to a 24% lower risk of death from any cause. The link was stronger in people who had already had a heart attack.

The authors noted their analysis did not account for other differences, like fitness or lifestyle. The American Heart Association has said people should not get a pet mainly to lower heart risk.

🌧️ DepressionBig reviews don’t show that dogs prevent depression.
Read more

A 2025 review of 21 studies found no clear link between dog ownership and depression risk, either up or down.

A 2018 review found people with mental health conditions mostly told positive stories about their pets, but the number-based results were mixed.

🩺 The honest bottom lineA dog can be wonderful support, alongside people and care.
Read more

Keep in mind

  • A dog is not a treatment for depression, anxiety or any health condition
  • Dogs bring costs, work and worry as well as joy
  • The best fit depends on your time, energy, home and money
  • Trained service dogs are a different thing from pet dogs
For psychiatric service dogs and emotional support animals, see “Therapy & emotional support animals”.

Walks, routine & getting outside

A dog who needs a walk can be the nudge you need on a low day.

Dog owners walk about 20 minutes more a day, on average, than people without dogs. But owning a dog doesn’t guarantee walks: only about 60% of owners walk their dog at all.

The strongest reason people do walk is the bond with their dog: a sense of duty to it, and the motivation it gives them.

🌳 A mindful dog walkTurn a routine walk into a small reset.
Read more

Try it

  1. Leave your phone in your pocket for the first five minutes.
  2. Notice your feet on the ground and your breathing.
  3. Watch what your dog notices: smells, sounds, other dogs.
  4. Name three things you can see, two you can hear, and one you can smell.
  5. Let your dog sniff for a while. Slowing down helps you too.
For more on nature and mood, see “Nature & the outdoors”.
⏰ Routine that holds youMealtimes and walks give the day anchor points.
Read more

Pets need care at the same times every day. People in research said this structure helped them, especially when their mood was low.

Daily anchors

  • A morning walk, even a short one
  • Breakfast for both of you
  • An afternoon play or training session
  • A last walk before bed
🪫 Low-energy daysShort and simple still counts.
Read more

Gentle options

  • A five-minute sniff walk around the block
  • A puzzle feeder or scattering food in the yard for your dog to find
  • Sitting outside together in the sun
  • Asking a friend or dog walker to cover one walk
On a hard day, doing the basics is enough. Your dog loves you on your low days too.
⚠️ Safe walkingMatch the walk to your body and your dog.
Read more

If balance is a worry, a strong or lively dog can be a fall risk. A calm dog, a short flat route and a well-fitted harness can help.

Larger dogs need more exercise. Think about this before choosing a dog.

Dogs as a bridge to people

Dogs start conversations and can ease loneliness.

Loneliness and social isolation are among the biggest health threats facing older adults, and doctors say dogs can help with both. When you are out with a dog, people stop to say hello.

💬 Easy conversationsPeople are drawn to dogs, and then to you.
Read more

Walks and dog parks give you chances to chat with neighbors and other dog owners. In research, owners said their animals helped them start conversations and build friendships.

Conversation starters

  • “What’s your dog’s name?”
  • “How old is she?”
  • “Do you know any good walking spots around here?”
🔁 Meeting the regularsThe same walk at the same time builds familiar faces.
Read more

Walking the same route at the same time often means seeing the same people and dogs. Over time, a nod can become a chat, and a chat can become a friendship.

🫥 If social contact feels hardGo at your own pace.
Read more

If you feel anxious around people, a dog can give you something to focus on. You can start with a smile or a quick “hi” and build from there.

For more on loneliness and ways to connect, see “Loneliness: understanding it”.
🤝 No dog? Borrow oneYou can enjoy dogs without owning one.
Read more

Ideas

  • Dog-sit for a friend
  • Visit a dog park and chat with owners
  • Volunteer at a shelter
  • Walk a friend’s or neighbor’s dog

Reading your dog

Happy, worried or upset: what your dog’s body is telling you.

Dogs tell us a lot with their bodies. Understanding their signals helps keep everyone safe, and helps you meet your dog’s needs.

😊 Happy & relaxedLoose mouth, soft eyes, relaxed body.
Read more

Signs

  • Mouth open and loose
  • Ears in their natural position
  • Weight spread evenly on all four paws
  • Tail wagging
  • Rear end up and front down, inviting play
😟 Worried or uneasyYawning and lip-licking can mean discomfort, not tiredness.
Read more

Signs

  • Low body and head
  • Turning the head away or avoiding eye contact
  • Tail tucked and ears pulled back
  • Yawning, licking lips or raising a front paw

A worried dog is telling you it doesn’t want you to come closer. Give it space.

😠 Upset: back offA stiff body, staring and showing teeth are warnings.
Read more

Signs

  • Stiff body leaning forward
  • Raised hair and a stiff, raised tail
  • Staring
  • Wrinkled nose, lips drawn back, teeth showing
  • Growling or snarling
Calmly move away and give the dog space. Don’t punish a growl. It is a warning that helps prevent a bite.
🪞 A lesson for usNoticing stress signals in your dog can help you notice your own.
Read more

Dogs show stress in small ways before it becomes big. People do too: tight shoulders, a short temper, wanting to hide.

Dogs, kids & bite safety

Most bites to children come from dogs they know.

Children are more likely than adults to be bitten by a dog, and their injuries tend to be more serious. Most bites to young children happen during everyday activities with dogs they already know.

👀 Always superviseEven with your own gentle family dog.
Read more

Young children should never play with a dog without an adult watching, including the family’s own pet. Pediatricians add that many bites happen during playful roughhousing.

✋ Teach kids dog mannersAsk first, let the dog sniff, keep faces back.
Read more

Simple rules for children

  • Always ask the owner before petting a dog
  • Don’t put your face close to a dog’s face
  • Stand still and let the dog sniff you first
🧼 Healthy habitsHandwashing and vet visits protect everyone.
Read more

Even a healthy-looking dog can carry germs. Wash hands with soap and running water after handling dogs, their food, bowls or poop, and before eating.

Take a new dog or puppy to the vet within a few days to a week of bringing it home. Keep rabies vaccines up to date.

🩹 If someone is bittenWash the wound and know when to get help.
Read more

Nearly 1 in 5 people bitten by a dog needs medical attention. Wash the wound with soap and warm water right away, and contact a health care provider if you are worried about it.

A dog bite can be frightening for a child. Afterwards, gentle reassurance and a calm return to normal routines can help.

Choosing a dog that fits your life

Energy, size, temperament and the honest time check.

The CDC suggests choosing a dog whose temperament, size and activity level suit your family, and researching dog care and local rules before you buy or adopt.

⚡ Match energy to energyA calm adult dog may suit you better than a puppy.
Read more

Pediatricians say an older animal is often a good choice, and that puppies may nip out of sheer friskiness. The same can be true for anyone with limited time, energy or mobility.

Ask yourself

  • How much exercise can I give on my worst week, not my best?
  • Do I have space for a big dog?
  • Who will walk the dog if I’m sick or away?
🏡 Adopting from a shelterMillions of dogs are waiting for homes.
Read more

About 2.8 million dogs entered U.S. shelters and rescues in 2025, and about 2 million were adopted.

Shelter staff can often tell you about a dog’s personality and energy level, which helps you find a good match.

💵 Count the costFood, vet care, training and more.
Read more

The ASPCA estimated (using 2021 figures) that a dog costs about $3,221 in its first year and about $1,391 a year after that. Costs vary by place and have likely risen since.

Dogs also need vaccines, check-ups, flea and tick prevention, grooming and often training.

⏳ “Not yet” is okayWaiting until you’re ready is caring for you and the dog.
Read more

If you can’t commit to a dog right now, you can still walk a friend’s dog, dog-sit, volunteer at a shelter or visit a dog park.

“Pets & your wellbeing” has an “Is a pet right for me now?” worksheet.

When dog life gets hard

Behavior problems, sick dogs and the stress nobody talks about.

Dogs bring joy, but also challenges. Feeling stressed or overwhelmed by your dog doesn’t mean you don’t love it.

🐕‍🦺 Behavior problemsBarking, pulling, fear or aggression can be exhausting.
Read more

A change in behavior can be a sign that something is wrong. The RSPCA advises speaking to your vet first. They may refer you to a qualified animal behaviorist.

Things that may help

  • A vet check to rule out pain or illness
  • Reward-based training classes
  • A qualified behaviorist for serious problems
  • Support from others who have been through it
Living with a reactive or anxious dog can feel isolating and embarrassing. You are not a failure, and help exists.
🩺 Caring for a sick or older dogCaregiver strain applies to pets too.
Read more

A study of 238 dog and cat owners found that people caring for a pet with a long-term or terminal illness had more stress, more signs of anxiety and depression, and lower quality of life than owners of healthy pets.

Ideas

  • Ask your vet for a clear care plan
  • Share tasks with family or friends
  • Take short breaks
  • Talk about how you are feeling
For end-of-life choices and grief, see “Losing a pet”.
🏠 If you need to rehomeSometimes it’s the kindest choice.
Read more

About 30% of animals entering U.S. shelters are surrendered by their owners. Life changes, like moving, illness or money troubles, can make keeping a dog impossible.

Contact a local shelter or rescue for advice. Choosing what is best for your dog, even when it hurts, is an act of love.

🫣 Feeling guiltyMissed walks and short tempers happen.
Read more

Nobody is a perfect dog owner. If you miss a walk or snap at your dog, take a breath, offer a kind word, and try again tomorrow.

Fill in “Our dog’s hard-day plan” in this guide so you have backup ready.

How community helps

Walking buddies, shelters and neighbors who share the load.

Dogs can bring a whole community together. Walks and dog parks create chances to meet neighbors and other owners.

When and where to get help

Your dog can comfort you, but it can’t replace human help.

Time with your dog can be a wonderful part of looking after yourself. It is not a treatment for depression, anxiety or any health condition. If you have been struggling for a while, talking to a counselor or your clinical provider can help.
