Benefits of Having a Dog: 8 Ways Dogs Make Life Better
The biggest benefits of having a dog are more daily walking, steady companionship, and a possible boost to your heart and brain health. The bond between people and their pets is linked to lower blood pressure, less loneliness, and more chances to exercise and socialize, according to the CDC.¹ In one large Australian study, people with dogs had about 23% lower odds of dying over four years than people without pets.²

Benefits of Having a Dog at a Glance
Most research on dogs and health is observational. It shows a link between dog ownership and better health, not proof that dogs cause it. Here's what recent studies have found:
Benefit | What research shows |
|---|---|
More walking | People with dogs walked about 17 to 20 more minutes a week⁵ |
Heart health | Walking or playing with pets can lower blood pressure and cholesterol¹ |
Longer life | People with dogs had lower odds of dying over four years² |
Brain health | Older adults with dogs had lower odds of disabling dementia³ |
Fewer food allergies | Early dog exposure was linked to fewer egg, milk, and nut allergies⁴ |
Responsibility for kids | Pet care helps children learn responsibility⁶ |
What Are the Benefits of Having a Dog?
1. You'll walk more
Dogs need daily walks, and that gets you moving, too. In an Australian study that followed adults for up to nine years, people with dogs walked more than people without dogs, about 17 extra minutes a week for women and 20 for men.⁵ The catch? People who had dogs but didn't walk them were no more active than people without dogs. The benefit comes from the walks.
2. Your heart may thank you
The CDC notes that regular walking or playing with pets can lower blood pressure, cholesterol, and triglyceride levels.¹ Those daily walks add up, and so does time spent relaxing with your dog.
3. You may live longer
In an Australian study of more than 15,000 adults, people with dogs had lower odds of dying over four years than people without pets, even after accounting for other health and lifestyle factors. Owning cats, birds, or fish showed no clear link.² Researchers think the extra physical activity from having a dog may explain part of the difference.
4. You'll feel less lonely
Pets can help manage loneliness and depression by providing companionship, according to the CDC. A dog greets you at the door, sticks by your side, and gives your day a steady rhythm. A dog isn't a replacement for mental health care, but that daily companionship matters.
5. Your brain may stay sharper as you age
A Japanese study of more than 11,000 older adults found that those who currently had a dog had about 40% lower odds of developing disabling dementia over four years.³ Those who exercised regularly and weren't socially isolated saw the strongest link.

6. Kids may have fewer food allergies
Growing up with a dog may help some children's immune systems. A Japanese study of more than 97,000 mothers and children found that dog exposure during pregnancy or early infancy was linked to a lower risk of egg, milk, and nut allergies up to age 3.⁴
7. Kids learn responsibility
Feeding, walking, and caring for a dog teaches kids that another living thing depends on them. "Taking care of an animal is a great way to learn about responsibility and caring for others," according to the American Academy of Pediatrics.⁶
8. You'll meet more people
Dog walks and dog parks are natural conversation starters. The CDC lists more opportunities to socialize among the benefits linked to the bond with a pet. A friendly dog can make it easier to start a conversation with neighbors.
What Are the Downsides of Having a Dog?
Dogs bring a lot of joy, but they're also a big commitment. Before you get one, think about:
Time. Dogs need daily walks, play, training, and attention, for many years.
Cost. Food, supplies, grooming, and vet care add up, so build them into your budget before you bring a dog home.
Young children. Because many dog bite injuries happen to young kids, the AAP suggests it may be safest to wait until your child is older than 4.⁶
Housing and travel. Check your lease, and plan for care when you're away.
How Can You Get the Most Out of Having a Dog?
To enjoy the benefits, make the healthy habits part of your routine:
Walk every day. The walks are where many of the health benefits come from.
Choose a dog that fits your life. Match the dog's size and energy to your home and schedule.
Make time to connect. Play, training, and quiet time together build your bond.
Keep up with vet care. Regular checkups help your dog stay healthy so you can enjoy many years together.
Frequently Asked Questions
Is having a dog good for your mental health?
It can help. The CDC says pets can help manage loneliness and depression by providing companionship,¹ and many people find that a dog adds structure and joy to their days. Still, a dog isn't a treatment for depression or anxiety. If you're struggling, talk with a health care professional, and think of a dog as one part of a healthy routine.
What are the benefits of having a dog for kids?
Kids who grow up with dogs get a playmate, a reason to get moving, and a chance to learn responsibility. Research also links early dog exposure to fewer egg, milk, and nut allergies in young children.⁴ Just make sure an adult supervises young kids around dogs, and teach your children how to approach and pet a dog gently.
Is it better to have a dog or a cat?
It depends on your lifestyle. Dogs need more time, exercise, and attention, while cats are usually more independent. Some health benefits seem stronger for dogs, likely because dogs get people walking. In one study, owning a dog was linked to lower odds of dying over four years, while owning a cat showed no clear link.² Both can be wonderful companions.
What age should a child be before getting a dog?
The American Academy of Pediatrics suggests it may be safest to wait until your child is older than 4, since many dog bite injuries happen to young children.⁶ Older kids can take on more of the pet care. Whatever their age, supervise young children with dogs and teach them how to treat a dog kindly.
