Identifying Tiny Bugs?

There is a small, tiny, hard to see with the naked eye bug in my bed, on my furniture, and on my dog. I can feel them on my face, but they're not really biting me. They are all over my house. Could someone please help me to understand what I have? I called the exterminator and they said it is not bed bugs so with this picture could someone please help me identify what is running me crazy?
