The best dog boutique is GlamourDog in Frisco (north Dallas area). Frisco is a pretty new and nice area. Here is glamourdog's website:
www.glamourdog.com They're right next to the Stonebriar Mall. There is also Foxy Paws in the Galleria and Zack and Zoes in Grapevine, TX (closer to Ft. Worth).
There are so many nice restaurants in Dallas. I love Ruth Chris for a good steak. La Hacienda Ranch is one of my favorite Tex-Mex restaurants. On the North Dallas Tollway, there are a ton of nice restaurants, especially right before you get to the Plano area.
There is a Zoo in Dallas, but the one in Ft Worth is a lot better. There is 6 Flags and Hurricane Harbor in Arlington. The Dallas Arboretum is really nice.
I know there are a ton of things to do and see in Dallas - hopefully someone else can give you some more suggestions
