She's a poop eater

I have a puppy. She is a five month old Austrailian Shepherd. She is
a poop eater. This is an obviously disgusting habit, but I understand
it is not entirely uncommon. I took care of this problem about 3
months ago, or so I thought. I put some hot sauce on her poop, and
when shye went to eat it, she did not enjoy the taste one bit. After
that, she wouldn't go near the stuff... till the last week or so. I
started puting hot sauce on it again, but apparently she figured out
that little trick, and only ate the poop unaffected by said hot sauce.
I figure I could just pick the stuff up, but tonight, she made it
obvious that that would be innefective. You see, we put her in a crate
when we leave, Well, she obviously pooped in her crate and ate it. I
know this, because not 15 minutes ago, she thrice puked up the most
vile smelling brown substance imaginable, I mean, it ranked right up
there with shad sides. And I do mean ranked. I need to get this
animal off of the poop. Can anyone please help me?

Crate is already that size, so that is out. I can regulate the
behaviour outside by cleaning up or simply being out there. She does
not spend long periods (well longer than 4 hours) in her crate at a
strech. Although I would perfer not to have her in there at all, her
behavour (ie chewing and housetraing problems) disallows me to leave
her free reign of the house when away. If we are going to be gone
longer, we take her to doggie day care. Any of this change anything?
