The Woodlands is a nice Area - have you checked with your vet ?  Some vets have daycare or day 'boarding' or may know a sitter...If I knew someone I'd suggest it or if you were closer I'd offer - I would LOVE to be a dog sitter lol !!   
Also - some Petco's and Petsmarts have bulletin boards where you might find numbers to call ...then check them out in person and see how you like the home.  Also - Groomers may know who does dog sitting too        |
