The 'Doggie Spa' is good. I'd go back, or rather, my dog would go back.
The spa side was a lower stress environment, and my dog came back an hour later smelling good, with a shiny coat, nails trimmed down well, and his ears squeaky clean.
I had a quick peek in the daycare area (basically a big room), and I wouldn't say it's an environment my dog would do well in. Too many dogs running around and not enough people. They also had toys (balls, ect) floating around, which can cause issues between dogs.
