What Is This??

Is anyone out there knowledgeable about entomology? If so, could you tell me what kind of bug this is? I've been finding them on my carpet in our house. They are dead when I find them, and they measure to be about an inch long. Of course my first worry is that it could be harmful to my puppy, but it might be nothing. Regardless, they give me the heeby-jeebies every time I find one.
