You guys use the rear door protectors? My doberman slobber (potent stuff) covers the door panel but the protectors all seem to ruin my tint film.
My Dobie's drool isn't an issue (well - yeah it gets all over the place but doesn't stain anything) but her brown (I imagine black ones too but I can never seem to pick them out lol) hairs get stuck to the underside "carpeted" type material on the bottom of the seats & the only damn thing that seems to remove them is strips of duct tape & that seems to pull some of the seat material along w/ it too hahaha - try as I might vacuming just doesn't seem to do the trick.
So my "method" is simply weathertech liner & a cheapo dog bed that I'll use for a couple months at a time until it gets too dirty & swap out for another $20 special. I always keep a couple "rag towels" in my truck too for quick cleanups, & I work out alot & get in/out of the truck sweaty nasty myself so I always have a beach towel in there I throw on top of the seats as needed, I'll drape it along the back of the rear seats to keep the hairs from sticking in when flipped up as I mentioned.
But nowadays I have at least a 5 and/or 1 year old in the truck + a dog so I'm not winning this uphill battle of keeping the interior "clean" I just go to town every 4 months on it & bring it back to better than showroom appearance, then in between im using quick sanitizer wipes & a rotation of rags/beach towels as needed to keep the interior from looking like a kennel crossed w/ a daycare crossed w/ a mobile office.....even though that's pretty much exactly what it is lol!!
Seat covers make no sense to me for my use since I always have 2 car seats in the thing, and even when the dog was getting a bigger slice of the pie in back before son #2 came along I ALWAYS kept the seat up & she got her cheap dog bed to lie in, if I had passengers getting in fold the seats down & voila - sparkling clean barely used leather seating
Weathertech floor liner in rear is a must for me tho
