Pets may support health by creating more chances to move, spend time outdoors, connect with other people, and feel accompanied. These are potential benefits, not guaranteed effects: owning an animal does not by itself prevent or treat depression, PTSD, heart disease, or other conditions. What a pet adds depends on the person, the animal, and the household.
Can pets improve your health?
They may contribute to wellbeing in several ways, but it helps to separate an opportunity from an outcome. A dog can prompt a walk; the walk is the physical activity. A pet can offer companionship; that does not make it a treatment for loneliness or depression. The U.S. Centers for Disease Control and Prevention (CDC) describes potential benefits and associations, not results every owner should expect.
Here are ten plausible pathways, framed with that distinction in mind.
10 ways pets may support health
1. They can create opportunities for regular movement
Walking, playing, and caring for an animal can add movement to a routine. The CDC says regular walking or playing with pets can decrease blood pressure, cholesterol, and triglyceride levels, while also describing pets as creating more opportunities to exercise. That guidance does not establish that pet ownership alone causes those changes.

2. Dog walks can make outdoor time easier to build in
A dog that needs walks may give its caregiver a practical reason to go outside regularly. The health value comes from the activity and time outdoors, rather than from simply owning a dog. A walk should suit both the person’s abilities and the animal’s needs.
3. They can encourage a more active routine
Pet care often involves recurring tasks rather than a single workout. Play sessions and walks can make activity part of the day. The National Heart, Lung, and Blood Institute (NHLBI) says regular physical activity strengthens the heart and can lower coronary-heart-disease risk factors, including blood pressure and triglycerides. Those established benefits of activity should not be attributed automatically to pet ownership.
4. Companionship may ease feelings of loneliness for some people
The CDC says companionship from pets can help manage loneliness and depression. The effect will vary, and a pet cannot replace human support or professional care. Animals also require attention and consistent care, which may not feel manageable for everyone.
5. They may provide a calming focus
Spending time with an animal can offer a comforting routine or a focus outside one’s own worries. The CDC includes anxiety among outcomes associated with the human-animal bond, but this should not be read as proof that a pet will reduce an individual’s anxiety or treat an anxiety disorder.

6. They may be part of a supportive routine for some people with PTSD symptoms
The CDC lists PTSD symptoms among areas in which the human-animal bond may be associated with benefits. This is not a claim that any pet prevents or treats PTSD. People experiencing symptoms should seek appropriate care; an animal’s suitability and training needs also matter.
7. They can create openings for social interaction
Walking a dog, visiting a pet-friendly space, or talking with others about an animal can create occasions to interact. The CDC identifies increased opportunities to socialize as a potential benefit. A pet does not guarantee that someone will make connections, but it may provide a natural reason to start a conversation.
8. They may support cognitive function in older adults
The CDC lists better cognitive function in older adults among potential benefits associated with pets. This is not a guarantee or evidence that acquiring an animal prevents cognitive decline. Any decision should account for an older adult’s preferences, capacity to provide care, and available help.
9. They may be linked with cardiovascular markers
The CDC summarizes potential decreases in blood pressure, cholesterol, and triglycerides in connection with regular walking or playing with pets. NHLBI separately explains that regular physical activity can improve cardiovascular risk factors. Together, these points support the value of activity—not a promise that an animal will improve a particular person’s test results.

Feeding, grooming, play, and veterinary care bring recurring responsibilities. For some people, that routine may feel meaningful and help organize the day. It is also a real workload: a pet’s needs continue when an owner is busy, unwell, or away, so the household needs a workable care plan.

A 2023 meta-analysis titled “Pet’s influence on humans’ daily physical activity and mental health” included 49 studies and 320,971 participants, and reported positive pooled results for physical activity and mental health. The authors also reported very high variation between studies. That heterogeneity means the pooled findings should not be treated as uniform effects for all people, pets, or circumstances; the indexed result does not establish a specific effect size for this article.
The distinction between pet ownership and activity matters. NHLBI describes health benefits of regular physical activity, including heart and mental-health benefits, but that is evidence about activity itself. A pet may help some people find reasons to be active; it does not ensure they will be, or that activity will be sufficient to change a health outcome.
How to decide whether a pet fits your household
Potential benefits are only one side of the decision. The CDC advises considering the animal’s lifespan, size, food, housing, exercise needs, veterinary costs, and who will provide care. Also consider household allergies, time away from home, and whether everyone can interact safely with the animal.
Recommended Free Tools
- Time and exercise: Can someone reliably meet the animal’s daily activity and attention needs?
- Space and housing: Is the home suitable for the animal’s size and behavior, and does the housing allow it?
- Care and costs: Can the household provide food, routine veterinary visits, and care over the animal’s lifespan?
- Shared responsibility: Who will feed, clean, exercise, and arrange backup care?
- Health and safety: Are allergies, immune vulnerability, young children, older adults, or pregnancy relevant to animal choice or care routines?
How to reduce health risks around pets
Animals can carry germs even when they appear healthy. The CDC notes that children younger than five, adults 65 and older, people with weakened immune systems, and pregnant women are at increased risk for certain animal-related illnesses. Practical precautions help reduce exposure.
Quick Recap
- Wash hands after touching or feeding pets, handling habitats or equipment, and cleaning up after animals.
- Keep up with veterinary visits and follow veterinary advice on vaccination, deworming, and flea and tick prevention.
- Use good hygiene around pet supplies and clean up animal waste promptly.
- Supervise children younger than five around animals.
- If pregnant, avoid changing cat litter if possible.
