I guess it depends on what you mean by "shave." Snorkels gets her hair cut very, very short but she's not bald.
We could not survive out here otherwise. There are little flat stickers that get between her toes, on her legs - and they are so tiny they are hard to find, get right next to her skin, and are very irritating. Plus the foxtails which poke directly into their skin and stay there. Cockleburs - if it pokes or sticks, we probably have it.
she grows these funky tufts of very thick hair on her legs that attract everything.
I've had long haired dogs out before and it was hell. Namely a chow. I didn't shave him but I had to cut so many cockleburs out he looked half bald.
I am glad Rebel has so little hair. He has only gotten one foxtail stuck in him and I saw it immediately. Of course, he has a natural shave.
