Was it really a chupacabra the blood sucking dog I saw yesterday evening, when driving home from work?

I live in Tuscola Texas, just off highway 83. I work as a state ranger, which I do a 2 day shift, as we rarely get any trouble around there. I was driving home from work yesterday evening, between rows of trees, no more than a mile from my house. My radio was buzzing as it usually does. My marshal calling into me now and then, and the beating of my wind screen wipers, which were wiping the dust which was blasting up onto my wind screen. My gun was holstered, a Glock 21, 9mm. All I could remember was that I was hot, and tired. I turned into a slight bend when I saw this black object cross my path, I stopped the car, turned on the wipers once more to wipe the dust from the wind screen, and I saw a dog. A hairless dog. I don't know whether it was a trick of the mind, but it's eyes were glowing mild red, not a strong red, a mild cinnamon brownish red color. I took out my pistol, as we're all told to shoot wild dogs, as most of the people in this area keep chickens and poultry. I opened the door of my car, and as the top of the door blocked my view, I couldn't see for a split second, when I stand up fully, the dog is no more than a few feet away. It's eyes are not glowing now, but it looks more like a hairless greyhound. It stand on it's rear legs, and hisses. I pull the trigger 8 times into it's chest. All I could remember then was blood which seemed to flow endlessly under my car. The dogs head was facing towards my right, I ducked under the roof of my car to tell my marshal I'd killed some sort of wild dog, when I stood up again, it's head was facing left. I slammed the door so hard, locked them, and sped off down that road, I didn't stop till I got home, my wife is worried about me, as I'm very shaken up recently, I've taken a few sleeping pills to keep me sleeping. I don't want to tell her what I saw, as I do not want to worry her, we all have heard of chupacabras around Texas, they're a famous blood sucking dog to remind you again, please, any answers would be great, just take the stress off my mind.
