Call the shelter before you bring an animal in. Many shelters and most rescues take owner surrenders by appointment only, some charge a surrender fee, and some keep a waiting list. Ask whether they offer a rehoming program or pet food and vet assistance first; many surrenders can be avoided with short-term help. The municipal animal control shelter is usually required to accept animals from residents of its city or county.

Start on the shelter's or rescue's own website: most post their adoptable animals there and on Petfinder or Adopt-a-Pet. Visit or call to meet an animal, then fill in an adoption application. Expect to show a photo ID, and if you rent, proof that your landlord allows pets. The adoption fee usually covers spay or neuter surgery, first vaccinations and a microchip. Fees vary by organization and by animal, so ask the shelter directly.
