I think Sunil's guess of "wolverine" is the closest to the shape of the animal in the photo, but they live WAY north of Texas.

However, who knows what exotic animals have been released in Texas?

The badgers on our farm (Kansas) always look much squatter than the animal in the photo, but their fur is usually hanging down, which accentuates the "squat" look. Do badgers shed their fur at the end of summer?

This is a fun puzzle! Did you get any more pics?
