A friend at home might be the secret to a longer, healthier dog life.
A big study from the Dog Aging Project looked at tens of thousands of dogs. It found that dogs with strong social support - often from living with another dog - were linked to better health.
Owners reported fewer diseases and better mobility. The effect of social support was one of the strongest factors they measured.
Some coverage also notes a link to longer lifespan. It’s not a promise, but the pattern is clear. More company, better odds.
Why might this help? Play and companionship reduce stress, keep bodies moving, and make daily life richer.
It’s not one-size-fits-all. Some dogs prefer being the only pet. Personality, age, and space matter. If you do add a second dog, match energy levels, do slow introductions, and keep routines steady.
Healthy relationships help us all - dogs included.
