One reason I chose Luna was because she wouldn't need much grooming.
I bathe her whenever we're going to do a demo, or whenever she rolls in cat poop outside.... usually about once every 1-2 months. I think I managed to go 4 months this winter. When she used to come to work with me every day, I'd bathe her more often , 1-2 weeks, because she'd be stinky more often; I think maybe from people petting her, I don't know.
I almost never clean her ears, I think I've done it about 3 times in the past 5 years. But I check them every few weeks, and when I give her a bath, just to make sure they're clean.
I'm very bad about doing her nails, but ATM I'm trying to shave her quicks back a bit so I'm dremmeling them twice a week. Generally I try to do them every 1-2 weeks.
My dogs at work get a lot more grooming, as it's much more important that we make sure they are clean and healthy. They get brushed usually 3-5 times a week - ALL dogs, even the short-haired ones - and get ears, nails, and teeth done every week. Most get baths about once a month, but that depends more on whether they go to foster homes or not; baths are low priority since brushing generally keeps them pretty clean.
