You have to get them under control inside and OUTSIDE of your house. IF your infested outside they WILL continue to come inside, via your clothes, shoes, pet, etc. For anyone that has irrigation at their home, there is a system that you can get to go with it. Sprinkler Magician is one of many out there that it hooks into your existing irrigation system and releases the treatment however much you deem necessary. It is all natural, so it does not harm pets or children and it really does work very well. It kills mosquitoes, fleas, ticks, No-See-Ums, knats, fire ants and just about any other kind of insect. There is also a product that you can put with it that deters snakes etc. There is a possibility you can install this yourself, however if you are not very handy have a licensed irrigation tech put this in for you. You would not believe the irrigation systems we have been called out to fix because people messed up installing.
Another trick for your pup is to wash in Dawn Dishwashing Liquid and don't bother with the flea shampoo, make sure to use a conditioner though as it is drying to the skin and hair
