I took data from the City of Houston’s Bureau of Consumer Health Services, which maintains a current list of bars and restaurants that have approved dog patios.
Effective September 22, 2011, owners of restaurants and other food establishments have been able to apply for a variance to the Houston Food Ordinance to allow dogs in outdoor dining areas.
I mapped the data using Google Maps for my personal use, and have made the map publicly viewable for other dog owners. While the weather is tolerable, take Fido out to dine with you.
The map can be viewed here: https://www.google.com/maps/d/edit?mid=znuw07LBYA-o.kQRaK4J-ORcc
