At wits end...How do I get rid of fleas?

I would say to go to a groomer or buy some pure o' flea shampoo, do a bath, wait a couple of days then do a spot on treatment (petco, petsmart has it) it's a kind of oily medicine you apply down the dogs mid back. Good Luck!! Sounds so annoying! Also depending on the breed you could get the dog shaved to make sure!!
