Harper was found by CPD on the side of a road huddled around a dead cat (likely hit by a car). Even in last week's scorching heat, she wouldn't leave the cat's side, enduring horrible sunburn on her emaciated body, and burning flesh off her paws on the cement.
My conjecture is that the "owners" abandoned their pets together. Now Harper is alone. I say -- cat people! Here is the dog you have been waiting for!
