Senior dogs — age 7 and up — wait far longer for homes than puppies, even though they're usually already house-trained, past the chewing stage, and happy to nap at your feet. Adopting an older dog in Arizona means you typically know their size, temperament, and energy level from day one: fewer surprises, and a grateful companion who settles in fast. Always confirm availability and adoption requirements directly with the shelter or rescue.

These organizations currently have at least one adoptable senior dog listed on Lily's Second Chance.
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.
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 senior dogs in one place so they're easier to find — the adoption itself happens through the local group.
Adoption fees vary by organization, but senior dogs are frequently discounted or sponsored because they wait the longest. Many rescues also begin any needed medical care before adoption. The dog's profile or the shelter can confirm the current fee.
Usually not. Older dogs are typically calmer and already trained, which makes the first weeks far easier than with a puppy. Some have age-related needs like a special diet or joint support, and the listing or shelter will tell you what to expect.
Yes. Most shelters and rescues in Arizona welcome adopters from anywhere in the state, and some can arrange transport within Arizona for the right match. Open a dog's profile to see the organization's contact details and ask them directly how their process works.
Senior dogs usually settle in faster than puppies because they're already past the most demanding stage. Expect a brief adjustment period — they may be shy at first, then relax into their personality. A consistent routine, a comfortable spot to rest, and patience are usually all it takes.
Many shelters and rescues in Arizona offer foster programs — sometimes with a foster-to-adopt path so you can try the match before committing. Fostering is especially valuable for senior dogs because it gets them out of a kennel and into a calm home while they wait for their forever family. Ask the organization on any dog's profile whether fostering is available.
Many senior dogs are calm, gentle, and well-suited to family life — but it depends on the individual dog more than anything else. The shelter or rescue caring for each dog can tell you their specific history with children, cats, and other dogs before you apply. Many organizations offer meet-and-greets to make sure the match is right for everyone.
Shelters and rescues can list adoptable senior dogs for free.
