Dogs aged 10 and older — in their double digits — are among the very hardest to place, yet they're often the gentlest companions you'll find: house-trained, long past the chewing and high-energy years, and content to spend their days close to you. Older dogs are too easily overlooked, so giving one a soft place to land for their remaining years is one of the most meaningful things an adopter can do. The dogs aged 10 and older listed right now include Hound / Mix, Mixed Breed (Large), and Poodle across 14 states. Always confirm availability and adoption steps with the shelter or rescue.

Adopting a dog aged 10+ — FAQ

What counts as a senior dog?

Most shelters and vets consider a dog "senior" around age 7, though large breeds often age sooner and small breeds a little later. Every dog listed here is 7 years or older.

Is it worth adopting a dog aged 10 or older?

Absolutely. Older dogs are typically calm, affectionate, and already trained, and they bond deeply with the people who give them a home. Their time with you may be shorter, but adopters consistently describe it as some of the most rewarding companionship they've known.

Do dogs aged 10+ have higher vet costs?

Some older dogs need a special diet, joint support, or more regular check-ups, but many are healthy for their age. Each dog's profile and the shelter caring for them can tell you about any known medical needs before you adopt.

How do I adopt one of these senior dogs?

Open any dog's profile to see which shelter or rescue is caring for them, then use the adoption link or contact details to apply directly with that organization. Lily's Second Chance gathers older dogs in one place so they're easier to find.
