If you want a city feel, you might like the Shops of Legacy location in Plano. Great restaurants, shopping and all within walking distance. You get the benefit of being in the suburbs with the feel of the city. Plano has a dog park and there is plenty of jogging/walking trails throughout the city. As a single person, I think this would be the area I would target for you first.
Don't hesitate to call or email if I can help.
