Nancy Greig, Director of the Cockrell Butterfly Center at the Houston Museum of Natural Science, tells the story:

Freddie is my dog, a 27 lb mixed breed, and this photo was taken in my back yard. Freddie’s quite the little hunter – fascinated by cockroaches at night and Anolis sagrei by day. The latter have become extremely abundant here in Houston in the last decade or so, out-competing/displacing the native green anole. There are dozens (hundreds?) in my yard. They tend to stay on or near the ground, unlike the green anole, which seems to prefer (especially now) to be higher up in the vegetation (so not of interest to Freddie, fortunately). Male A. sagrei can get quite large and as you can see here, pretty feisty! The standoff lasted several minutes, and was repeated several times. But I’m afraid Freddie got the better of the plucky fellow in the end.
