I vacuum every 2-3 days in the areas they frequent most, yet I still have hairy dust kittens floating around ... it’s just part of the price I pay for having 3 Labs. We just got rid of the carpet in our family room and replaced it with luxury vinyl. I love it, but it does show the dirt/hair more ... but on the other hand it’s MUCH easier to clean than carpet so ...
I haven’t particularly noticed the vacuum (we have a Dyson) smelling most of the time - if it does, I clean out the filters, dirt tank, etc and it seems to help. Usually vacuuming the whole house requires emptying the tank mid clean.
Dog beds I don’t wash as often as I probably should - maybe once a month if that? I haven’t really noticed them getting stinky though. Don’t know if I’ve gone “nose blind” or if my dogs just don’t really smell that bad. Mulder was stinkier than any of the girls, so I tend to think it’s not completely that I don’t notice it. We too keep blankets on the couch and bed that get washed at least once a week if not more. The car isn’t bad, but they only ride in crates (we have a minivan) which contains the hair.
I know what you mean about the differences between the blacks and yellows. Chloe sheds horrendously but it’s only for about 2-3 months out of the year, but the yellows so far shed little bits daily.
I feel your pain though - I just locked all the dogs in the yard for a few minutes so I could clean the floors (they go crazy biting and barking at the vacuum which is a PITA to deal with), and while they were out, they decided to run through some mud puddles so as soon as I let them back in, the floors were dirty again. Sigh ....
