Fleas!!

Hey guys/gals...we've got a problem!

Tira and Gunner both have fleas. The house has fleas and probably the yard as well. We've sprayed the yard, to no avail. We've bombed the house, to no avail. We've shampoo'd, flea collared, used preventative, capstar, etc. - all to no avail. I don't know what else to do?!

I have to bathe them once a week with a flea shampoo that's supposed to last a month (kills fleas, eggs, ticks and larvae). Why does this shampoo not keep the fleas away - even though the shampoo says it's supposed to last for a full month????

Gunner and Tira are both starting to thin out on the top of their back from nipping and licking trying to get rid of the itching. It's not a lot, just on one side about --------------------------------------------------------------- long and ---------------------- wide. There are no scabs, no redness, but the hair is thin.

HELP US !!!!
