Tesla, Polestar, and other battery-electric vehicles carry the same One Time Price as every listing. Hybrids and plug-in hybrids are on a separate page so you are not shopping the wrong list.

Frederick · actual neighbors
The photos and write-ups come from the shelter. We just give them a front door, because a Frederick family might be the one they are waiting for.
A family store helping shelter babies find a family.
When the shelter sends photos, they land right here. This is the welcome sign until then.

Adoptions are by reservation. Dog adoptions are not same-day — the shelter interviews families and often needs 3–5 days.
At the store, ask for Renda. She looks after this every week.
