Cynoscion

It’s a canine of some sort. If that odd drag track wasn’t there, we wouldn’t be having the conversation so it’s most likely an anomaly unless you could follow the track and see it in repetition. The only canine track I know of from south Texas that will leave obvious claw marks is a domestic dog. Our coyotes generally leave 2 visible toenails but not all like your track which is why I would say domestic dog here or possible wolf where you are.
