nini you need to get some proper flea treatment from the vet and your home will need to be sprayed, with something from the vet as there will be fleas and eggs on your furniture and floor, or wherever the dog has been. If you don't treat your home as well as your dog then your dog will become infected again very quickly. Only the vet can provide you with an effective treatment. Advocate is very good, don't get Front Line Spot-on as that is no longer effective. Your poor dog needs to go to the vet asap as it will be driving him crazy.
