He was the ONLY dog there wearing a collar. A blaze orange hunting collar.
I was driving around looking for him, and when I couldn't find him I called them. Good thing too coz they were about to close! I asked if they'd had any calls about a yellow Lab near the park that he'd been out about an hour, and she says to somebody in the background "where did you pick up that yellow Lab?" - two streets over from me. I asked if he was wearing an orange collar? Yes. So I asked if I could come get him now. They asked about my vet and his rabies tag and all that jazz and said to hurry because they closed at 4:30 (it was like 4:15)
He's super friendly, it's not like it would have been hard to take a second look at the brass tag on the neon orange collar . . . . duh. I could understand if he was semi-aggressive or didn't want to be handled, but he's not at all.
They are a true animal control office, not a rescue/shelter type place. I don't think they keep dogs very long. Considering that he was the ONLY one with a collar, and obviously neutered and taken care of, why not give that collar a second look?????
ETA: and yes I had to pay like $25 to get him out, which didn't seem too bad really. And they let me in after they had closed the gate, because they knew I was coming. They weren't terrible about it, but I wouldn't have had to rush so much if they had called when they first got him to the shelter.
