Availability changes often as dogs are adopted and new ones are listed. If you don't see a senior dog in Arlington right now, check back soon or browse all of Washington — new dogs are added regularly.

Adoption fees vary by organization, but senior dogs are frequently discounted or sponsored because they wait the longest. Open a dog's profile or contact the shelter or rescue directly for their current fee and any covered vet care.

Most senior dogs have a brief adjustment period — a few days to a couple of weeks — as they settle into a new home. They're often shy at first, then relax once they feel safe. A calm routine, a comfortable place to rest, and patience make the transition easier for both of you.
