Very unlikelytomorrow!!! Yay! But back to the poop eating. Neither of them have worms either. So she's not losing any nutrients from intestinal parasites. Like I said, I've pretty much narrowed it down to a Vitamin B deficiency based on my Googling 'poop eating'.
Deterents like tobasco, distaste and meat tenderizer in studies are miminally successfull. The only truely successfull technique is to clean up immeadiately after the dog.

Now if you would like the real reason dogs do this they have over a 17,000 year history of doing so, see
How Wolves became Dogs
studies on deterents like distaste and meat tenderizer show them to be only minimially effective. The only sure way is to clean up imeadiately after the dog goes.Jonica Newby: For a long time scientists believed our nurturing instinct was enough to explain the relationship. We created dogs for our purposes. Man tamed the wolf - as a pet. But one outspoken professor of evolutionary biology thinks the pet theory of domestication is all just a fairy story.
Prof. Raymond Coppinger: How does it work where you go out and you bring a puppy back to the village and you make a pet out of it? And then what happens? A miracle happens, fairy godmother comes and turns it into a dog. How does it turn into a dog?
Jonica: it seems to me pretty reasonable that they go out and get pets. You know they go and get wolf cubs and so on. What’s wrong with that idea of domestication?
[FONT=arial, helvetica, sanserif]Prof. Raymond Coppinger: Well first of all wolves are just trained to run away from you. I mean they’re going to hide their little … isn’t this a much better model. You develop a better mousetrap. You develop a village. You get food in the village. Guess who comes? All right. Now you want to postulate some great scene where I’ve got to go out into the wilderness to get those things. Which one looks, which one looks easier to you? Far from we humans domesticating them, dogs invaded us. Not as pets, but as pests.
.. it’s the rules of natural selection. It’s Darwinism if you will. They’re coming to the food. They’re coming to the waste products and the thing about humans is that there’s tremendous numbers of waste products. Scavenging on village wastes was a wonderful strategy for the early wolf-dog - and maybe they weren't such a complete nuisance after all. Rubbish dumps breed disease. A mobile post-pleistocene garbage service might have come in handy. And it could help explain the dog's least endearing habit. Eating shit.
Why Do Dogs Eat Poop?
Here's more than you probably want to know about coprophagia.
1) In the short-term, if a dog is eating its own feces, coprophagia is both a normal and common canine behavior, and a harmless one. If the dog is ingesting the feces of other dogs or animals, it may run the risk of picking up a parasite or virus from the "donor." However, if the coprophagia is occurring among your own animals, there is little danger as long as you are keeping them healthy and providing the necessary vaccinations and heart worm medication. (The one exception may be young puppies that have not yet gained full immunity from parvo through vaccinations.) In the majority of cases, the behavior eventually stops on its own after a number of weeks or months. It is most commonly seen in pups between 4-9 months of age, who will most
...A) Everyone and her brother has a magic food ingredient that supposedly will prevent coprophagia, from pineapple to spinach to pickles--including all the commercial additives. Although some of these "supplements" seem to work for particular dogs, there is no certainty or guarantee that they will work for your dog. Statistically, most of the time food additives fail to stop the behavior. A behavioral reason for this, which the members of this list can appreciate, is that eating the feces is simply more reinforcing than the "nasty taste" is punishing. There is also a possible physiological reason for the failure of food additives. Dogs have survived is by developing a tolerance for what we would consider nasty tastes. As Nancy points out, dogs are scavengers and opportunists. (See the Coppingers' book, "Dogs," and their village dump theory.) Some studies suggest that dogs that engage in coprophagia, especially long-term, have an even more forgiving sense of taste than the average dog.
...) Although it was once thought that dietary deficiencies were a cause of coprophagia, most studies to date fail to show a clear or consistent correspondence between dietary deficiency and the unwanted behavior. Some dogs with nutritional deficiencies have ceased being coprophagic after their diet was improved, but as with the nasty tasting food additives, no particular nutrient seems to help all coprophagic dogs, and a majority of coprophagic dogs have no measurable deficiency. When a deficiency is associated with the behavior, it has most often turned out to be thiamin or one of a few trace minerals. So supplementation with a B-vitamin complex rich in thiamin may help some dogs. The link here is still tentative, though, because in a number of studies dogs that were deprived of nutrients did not become coprophagic. So while some coprophagic dogs have a nutritional deficiency, all dogs with deficiencies do not become coprophagic, and all dogs that are coprophagic do not have a nutritional deficiency.
