Location is the San Francisco Bay Area.
I tried the [dog training] search on two different browsers...
- one with long-accumulated Google cookies but not signed in
- the other with cookies flushed, also not signed in.
On this search, I get same results in both browsers, and, for a half-hour window, anyway, the top three were extremely consistent, as were the others I'm noting...
