Doggy DayCare Fan here too! Katy goes to day care twice a week. A couple of my friends and I have started play date days there. Katy absolutely loves it. When ever we say "ready to go to Carols" She runs to her bow box and starts barking. When we get on the road and start the turn off to the daycare, Katy starts going nuts.
She runs to the door, and barks for Carol to let her in. She then flys to back and greets each and every dog.
They have 2 general social areas inside, one for big dogs and one for little (Katy takes turns, she loves to play with both). She also has 4 large sections on play runs outside.
They charge $15 a day or you can buy a weekly package for $70 and use the days when you want.
I can not say enough good things about them.
