Tiny Black Oval Bugs?
I had cigarette/drugstore bugs last year, and that sounds like what you may have. They were a pain to rid of, but so far dont have them again. Check out site about this and see if the info helps you.
What Breed is My Dog?
Looks like a Jack Russell to me. I have one that just turned 12 (2/27/09), and she weighs about 16 lbs... They ARE wonderful pets,but you have to be stern with them or they control YOU!!!
