Boarding Needed For 1 Or 2 Dogs In (or Close To) Takoma Park

I am actually looking for long-term boarding/temporary home for my Golden Retriever and Mixed breed dog Both are large (70-75 pounds). I am a teacher going overseas next school year and need to find care for them from approximately AUGUST 10, 2025 THROUGH THE END OF JULY 2026. (About a year) Simba is 4, sweet, in good health, and gets along with other dogs and people. Comet is 10, in good health for an older dog. She loves people, but not other dogs (besides her brother), so can not be in a home with other pets. No medications for either one. Please respond only if you can board one or two dogs for a year, and we can discuss a monthly rate Ideally, I would like them to be together, but will split them up if I need to.
