Unless they had been gone for days or weeks your dogs aren't gonna look starved and abused. That's the difference. Keep them and keep quite.
I agree 100% in this particular case, that the OP should keep and take care of these two dogs. But, I have personal experience that things aren't always so cut and dried. A few years back, I had a Malamute that my wife and I treated better than most people treat their children. During the day, Max was a backyard dog - it wasn't physically possible to make him stay in the house while we were away at work. One hot hot hot Houston summer day, he decided to dig out of the back yard and spend the day wandering the neighborhood (Malamutes are tunnel and escape experts) . Toward the end of the day, a man down the street managed to grab him by the collar when he tried to drink from a sprinkler (a brave man - Max looked more like a wolf than a dog - think Dire Wolf from Game of Thrones). He got his address from his collar and brought him back, for which I was grateful. But he then proceeded to build into a towering rage at me for how I was mistreating this dog by not providing adequate water. Max did look thirsty, what with the heat and his arctic fur coat. I had to show the guy that Max had escaped from a back yard that had a pond, a kiddy pool full of water, and several full water dishes before he calmed down and gave let me have the dog. So anyway, just wanted to say that things aren't always what they seem - although, like I say, the story with these two dogs seems pretty straightforward. Max only escaped the yard twice, thanks God - as far as Malamutes go, that put us way ahead of average.
