Adopting a senior Mixed Breed — 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.

How do I adopt a senior Mixed Breed?

Open a dog's profile to see the shelter or rescue caring for them, then follow the adoption link or contact details to apply directly with that organization.

Are senior Mixed Breed dogs a good fit for first-time adopters?

Often, yes. An older Mixed Breed is usually past the high-energy puppy stage and may already know basic commands, which can make ownership easier to ease into. Each profile and shelter can tell you about that dog's individual personality and needs.

Why adopt a senior dog instead of a puppy?

Senior dogs are calmer, usually house-trained, and let you skip the chewing and sleepless nights — and because they are the hardest to place, adopting one can quite literally save a life that might otherwise run out of time.

Know a senior dog who needs a home?

Shelters and rescues can list adoptable senior dogs for free.
