Treat the doge with flea meds, then that should take care of the ones on the doge. As for the ones in the house a good flea trap works 1. Get a desk lamp, large shallow plate, dish soap. 2. Fill the plate with water and place in any room. Put a couple drops of dish soap in the water, as this breaks the surface tension. Shine the lamp on the water (fleas love shiny things) and let sit overnight. The thing will be filled with dead fleas very soon.
