Our female boston ate her poop ALL the time when she was a pup. She was kept in a oversized crate, but it was the plastic kind with the holes. Everyday we would come home to discover she had pooped and had eaten it. We talked to the vet about it and she suggested the medicine that you give them that's chemically changes in their digestive system to make their poop less appealing, like it isn't already . So, we quit the medicine and then decided to try a different crate. We purchased the wire, more open kind. The pooping completely stopped. I almost didn't believe it at first, but it did.

However, Chloe still will occasionally be discovered eating her poop outside. We have no idea why, and she doesn't do it all the time. So, maybe there are some dogs that just do it...... We still love her!!!
So, I hope this gives you hope that maybe she'll grow out of it!!

I have also heard that sometimes dogs need smaller spaces to stay in when they are left alone because by nature they are "den" like creatures. Our other dog Duke used to pee when we were gone(we left him out in the house) and so we started closing him up in our bedroom along with Chloe in her crate, and the peeing stopped!!
