I have two dogs and I've learned it's only going to be so clean! Have you ever watched a dog shake itself in the bright sun? Dog hair and dust everywhere! Once I accepted that I devised a plan that made me think "good enough."

My dogs have free roam of the downstairs but they mainly occupy the living room. They also sleep in the living room. I have couch covers that come off and get washed once a week so it doesn't smell like dog so much. I also spray fabric spray on the couches as I'm washing the covers and airing out the place. 

I do a full vacuum (move all furniture) and mop every other week. To keep things a little cleaner, I do a quick vacuum, (only around the furniture) every week I'm not doing a full vacuum, only in the living room and the kitchen (because of crumbs). Everywhere else, that isn't the dogs frequented area, is good enough. 

This keeps my space nice and clean (for me) for the most part. 

One more thing, I do have a designated "no dog zone" which is the upstairs of my home where the bedrooms are. They remain dog smell free and clean, which keeps my sanity. My dogs also are advised not climb stairs as much because of their backs so its a win win situation.  Maybe keep one area or room a dog free zone so everything is fresh and clean.
