Advantage II, get it. The two main ingredients feature: A neurotoxin to disrupt the flea's motor functions. They will starve and die because they're disabled. A growth inhibitor to prevent larvae from growing. This will eliminate their food source (your dog). From there, get a carpet powder to kill the eggs. Fleas will jump off your dog to lay eggs, therefore they are on your carpet. There isn't a chemical to kill eggs, you rely on something to dehydrate them. Also get a spray for your furniture, and wash any other cloth in hot water. Do [i]not[/i] rely on flea shampoos. It will kill the fleas on your dog, but it will only last a day at best considering the fleas will just jump right back on. Flea collars are not effective, and can further irritate your dog's skin. Under prime conditions, fleas can live quite a while without food. It's important to treat your home with powders/sprays and through cleaning, otherwise they can outlast the treatment for your dog (it's a monthly treatment). Just follow the directions/safety guidelines on whatever you get to ensure you and your pet's safety while the treatments are out. Otherwise, vacuum a lot. Vacuuming will get rid of 98% of the fleas/eggs/larvae on your floor. If you want to go crazy, put a portion of a flea collar in the vacuum bag [i]after[/i] vacuuming (if you do it during, you'll be inhaling all sorts of nasty crap) to ensure they're dead and can't come back somehow.

Frontline is a good brand as well, but they lost their patent on Fipronil (the main ingredient), so a bunch of cheaper companies have hopped on with relatively ineffective and questionable products. I can't recommend them. - Your dog might still be itchy for a while after being relieved of fleas. Flea bites leave scabs that cause irritations, much like mosquito bites. There are soothing sprays and such you can use. - If you opt to not treat your dog, he/she might itch until the skin is broken and it can get infected, otherwise known as a hotspot. Get on it bro. You can provide temporary relief by bathing your dog and thoroughly combing him/her. This will flood the undercoat and drown the existing fleas. No shampoo is necessary, and be gentle. - If you're on the fence about using chemicals on your carpet, salt will work as well. As I said, the point is to dehydrate the eggs, chemicals can't penetrate the shell. Vacuuming is extremely effective, but you might miss some spots. Fleas reproduce very quickly, so a few missed eggs will lead to a future infestation. Consult a vet if you want more information on what you can do.
