Pets provide emotional support and routine benefits but should not replace professional help

Research shows that pets offer comfort, lower stress, and foster social connections, but experts warn they are not a substitute for professional mental health support during distressing times.

For many families, a dog waiting at the door or a cat seeking a stroke is part of daily life. But the emotional value of pets goes well beyond routine companionship. According to psychologist Mariane Pires Marchetti, living with an animal can bring affection, comfort and a sense of connection, and it may matter just as much in difficult periods as in happy ones. Research reviewed by outlets including PetMD and WebMD also points to lower stress, less loneliness and improved mood among pet owners.

That support often comes from simple, repeated moments. Playing with a pet, taking it for a walk or even sitting quietly with it can offer a brief break from worry and intrusive thoughts, Marchetti said. Studies cited by ScienceDirect suggest that contact with animals can meet basic psychological needs and is linked with greater psychological well-being, while research on older adults indicates that pets can also encourage social contact and community engagement.

Pets can also give structure to the day. Feeding, grooming, cleaning up after an animal and keeping up with vet care create regular responsibilities that can help people maintain a routine. Healthline and WebMD note that this kind of daily care can be grounding, especially for people who feel withdrawn or overwhelmed. For some, that sense of duty also brings purpose at a time when they may be struggling to find it elsewhere.

The benefits, however, are not automatic, and the relationship matters. A study published in the Journal of Adolescence on teenagers with social anxiety found that closeness to dogs and involvement in their care were linked with more adaptive ways of dealing with stress, such as problem-solving, emotional regulation and positive thinking. But the same research found that seeing a dog as a substitute for human relationships was tied to less helpful coping strategies. In other words, a pet may support emotional health, but it cannot replace people.

Marchetti said the limit is especially important when distress begins to affect everyday life. Persistent sadness, anxiety, isolation, frequent crises or difficulty carrying out normal tasks are signs that professional help may be needed. Pets can be part of a wider support network, offering warmth, routine and companionship, but they should not be expected to carry the full burden of someone’s mental health.
