Yes and No. Fleas actually prefer animals like a cat or a dog to feed off of. If a flea has a choice between your blood and the blood of your dog, they will choice your dog, but what happens is sometimes you can have an infestation of fleas so they will just jump on any host "Dog, cat, human" to get their meal.
Best way to tell that you have fleas in your home is to look at your dog's tummy usually around the back end or even their butt itself. You can see one or two of two things: 1) Flea "Dirt". It's tiny hard pieces just like dirt on your dogs skin which is actually flea poop or 2) You will see little black dots almost move around which is the flea itself. Sometimes you will not see the flea itself but almost always see flea dirt. If you don't physically see fleas but see flea dirt then your animal or home has fleas. You could also try a flea comb or a lice comb. You can get them pretty cheap at any Pet store and some regular grocery stores have them. It's a small comb with the teeth small and very close together and then brush your dog with the comb. That's a good way to see fleas or flea dirt.
So yes, fleas will bite humans but they do not prefer them.
If you find fleas or flea dirt then you want to get your animal on some kind of flea preventative like Frontline, Revolution or Advantage. Maybe buy some flea shampoo and give your dog a bath but that only lasts a few days. Run your sweeper over the carpet. Everyday is usually the best option and if your vacuum has the bags that collect everything you sweep up, immediately throw the bag away when you are finished so the fleas can't get back into the house.
One more tip that I found online awhile ago to get rid of fleas in your home is to leave one day for a few hours taking all your animals with you, close all windows and crank up your heat, usually around 90 or so degrees F. Fleas die in heat that high and it is suppose to bake them.
Hope this helps
