Adopting a senior Mixed Breed in Florida — 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 in Florida?

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

Are there always senior Mixed Breed dogs available in Florida?

Availability changes often as dogs are adopted and new ones are listed. If you don't see a senior Mixed Breed in Florida right now, check back soon or browse nearby states — new dogs are added regularly.

Can I adopt a senior Mixed Breed from Florida if I live elsewhere?

Often, yes. Many rescues and shelters in Florida 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.
