Senior Chihuahua dogs in Arizona
Meet 27 adoptable senior Chihuahua dogs (age 7+) in Arizona. Each one is from a shelter or rescue and ready for a calm, loving home.
Older Chihuahuas in Arizona are often passed over for puppies, yet they're usually house-trained, settled in temperament, and ready to bond right away — and because they're fully grown, you already know their size and personality. Adopting a senior Chihuahua in Arizona means welcoming a calm, grateful companion who can settle in from day one.

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 the shelter or rescue caring for them in Arizona, then use the adoption link or contact details to apply directly with that organization. Lily's Second Chance simply gathers senior Chihuahuas in one place so they're easier to find.
Availability changes often as dogs are adopted and new ones are listed. If you don't see a senior Chihuahua in Arizona right now, check back soon or browse nearby states — new dogs are added regularly.
Often, yes. Many rescues and shelters in Arizona arrange or help coordinate transport for the right adopter, while others prefer a local meet-and-greet first. Open a dog's profile and ask the organization directly how their out-of-area adoption process works.
Shelters and rescues can list adoptable senior dogs for free.
