Thanks for all your information. Yesterday, I gave him a bath with dish soap which took off a few fleas. He looks much cleaner now

I have been using Advantage on him and the vet recommended that I use it about every 2-3 weeks because the fleas are horrible here right now. It is very hot right now. I also live in the woods which definitely does not help matters. The vet recommends Advantage because with Frontline they told me, and I've heard, that the flea actually has to bite the dog for it to die which doesn't help the scratching. With Advantage, once they come in contact with it, they die. Thankfully Fargo's fleas haven't gotten out of control yet. One of my coworkers has them much worse. She has bites all over her ankles. Ugh! Hopefully we can rid them before it gets like that!
