Meet 60 adoptable senior Terrier dogs (age 7+) in California. Each one is from a shelter or rescue and ready for a calm, loving home.

Adopting a senior Terrier in California — 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 Terrier in California?
Open any dog's profile to see the shelter or rescue caring for them in California, then use the adoption link or contact details to apply directly with that organization. Lily's Second Chance simply gathers senior Terriers in one place so they're easier to find.
Are there always senior Terrier dogs available in California?
Availability changes often as dogs are adopted and new ones are listed. If you don't see a senior Terrier in California right now, check back soon or browse nearby states — new dogs are added regularly.
Can I adopt a senior Terrier from California if I live elsewhere?
Often, yes. Many rescues and shelters in California 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.
Know a senior Terrier in California who needs a home?
Shelters and rescues can list adoptable senior dogs for free.
