I don't brush at all lately and give her a bath every Sunday. I have wood and tiles floors, so I can feel all the dirt when I walk barefoot. And if it's bad enough, I have to brush it off the bottom of my feet before I get in bed. So, I generally sweep every other day and vacuum and mop once a week.
I haven't washed her new bed since she got it a month ago. How would even wash something like this?
One of our dogs has one that is pretty similar. I just throw it in the washing machine and put it on the bulk cycle. Granted my machine doesn't have the big agitator in the middle like some models so it's a bit easier for me. The other dog bed goes to the washateria as it is just way too big for our machine. Plus he is the dog that tends to shed the most and I don't want his hair killing another washing machine drain motor.
