I have a 12 week old puppy and she has these brown and black bugs, I think they are lice but not to sure... Its to expensive to take her to the vet so I'm hoping to find some answers.

Frontline Advantage is 'expensive' but cheaper than a vet, and kills any bugs. Buy some ASAP and apply according to the dog's weight to the back of the neck.
Don't try the cheaper brands in pet stores. They don't WORK, period. Neither do collars.

Joypulv is right... it takes some power to kill most bugs on dogs.

Still not sure what you have, but am suspicious they're baby ticks. If you need a magnifying glass to see one very well, it's probably a newly hatched tick. They have only 6 legs, and are fairly dark colored. Many could be attached and feeding, so you may have to pull it off unless you can get a good look otherwise.

I have added a link to this supposed tick. It is unusual in that it will live in a house all winter long in cold climates. Lack of humidity is usually fatal to other types, but not this one. The female is big and fat, like a large swollen grape. It drops off the dog, climbs up (usually the wall) to get behind a picture frame, where she will lay a 'raft' of hundreds of eggs... all neatly deposited one layer thick on the wall. She then dies, and usually her shrunken body will be found at the base of the wall, under wherever she laid her eggs. If this isn't working for you, take a few of the 'bugs' in a small container of rubbing alcohol (it kills them) to the vet for an ID, or to someone else who won't charge you just to look. Pet store ? (ask the boss if anyone else just guesses).

Lice are white, and they will lay their eggs on the hair, where they look like tiny white drops, well attached to the hair shaft. Lice are very particular who they live on. People lice will not go aboard a dog, for example.

Here is the link. It's long, but info is good. There are a few pictures, but you can Google the name of the tick for other sites that have more. http://www.bugs.ufl.edu/creatures/urban/medical/brown_dog_tick.htm
