Ok we noticed fleas on our dogs about TWO MONTHS AGO. So we treated them with Frontline Plus, used a flea shampoo, and vacuumed the entire house and mopped every single day. We continued to find fleas so we continued to give them flea baths, apply frontline every 3 to 4 weeks and vacuum and mop with soapy bleach water EVERY DAY and we treated our yards. Finally two days ago we discovered a million fleas all over our dogs so we bought flea bomb, bombed the house, came home VACUUMED, MOPPED with bleach and soapy water, AND sprayed flea spray on our animals. Today they STILL HAVE FLEAS. HOW can we get rid of these **** things. Also my dog is an Aussie/Border Collie mix so his fur is VERY thick. I am against shaving him because it is unnecessary to cool him but should I shave him to get rid of the fleas? Also if I don't shave him can a groomer thin his hair out so at least maybe the shampoo will work better? I mean I lathered and covered him in flea medicine for about 15 minutes and I also brush his coat every single day. Please HELP!
