I hated Gonzo when he did that exact same thing. I was dog-sitting for my friend's Aussie who Gonzo has a love/hate relationship with. I was pissed because it just felt like he did it to spite me... I know it isn't like that, but that's how I felt when I woke up at 7 am to a horrible stench.
The crate is in my closet, so he not only covered his crate in ****; but also all around the crate, and in some of my shoes next to the crate! I had to drag the crate out of the closet to clean it, and in the process left poo trails in the carpet. I picked him up out of the crate, stuck him in the bathtub, told him to stay and turned to shower on while I cleaned up the carpet. Lucky for him, he stayed in the tub! I then went to the store and rented a carpet cleaner.
Pooing inside grosses me out sooooo much. It makes me physically ill. And Gonzo has a sensitive stomach, and he's super emotional, so it is something that I have to deal with at the most inconvenient times.
Once the smell and stains are gone, I'm over it. But until then I just keep him away from me so he doesn't pick up on it.
You could try adding some pumpkin to her food. It will keep things moving, and firm up her poops. You might also switch her food.
