Well dogs get fleas mainly from sleeping in dirt of coming to close contact with another animal with fleas.
To get the rid of them, you can spray your yard with high scented chemical (which is illegal in populated areas), visit your veterinarian and get some pills for the dog, or buy a flea collar.
Dogs may not swallow pills and it's not a good idea to dissolve it in it's water. When my dog gets the pills, I get a tin of canned sausage links and cut a slit in one, insert the pill a give it to the dog. That's the easiest way, TRUST ME.
They have products out there that will keep the fleas & ticks off of your dog for a month. That would be Frontline, Advantage, BioSpot (doesn't seem to work as well). I personally like Frontline, will not wash off and you only put it on your dog's skin once a month and it does keep those fleas & ticks off.
Fleas suck the dogs blood, and causes itch. The flea is a parasite to the dog.
He probably has an itch on his skin and he is trying to relieve it.
no
Scratch it.
Nope. All fleas are the same. There's no human flea, cat flea, dog flea, or any certain flea. They're on everything. A human could possibly get sick if they had a reaction to a flea bite (unlikely), but flea bites only itch. Trust me, I know. I attract fleas *and* mosquitoes, and all those other horrible things.
Flea!
try rubbing vinegar on youself or rubbing alcohol also calamine lotion helps relieve the itch

You scratch an itch! An itch itches. You scratch an itch to remove the pain.
All dogs itch
Scratching an itch can temporarily relieve the sensation, but it can also damage the skin and make the itch worse in the long run.
To relieve the itch, an oatmeal bath.
