Aw, poor little girl. That's painful! My Puddy went through that just a few months ago. I came home from work and found her lying on her belly in the litter box, crying. She had really thick mud-like poop stuck to her behind. Dr. Lee, rather than give her an enema, palpated her abdomen; that didn't work. So the sweet girl had to be put under anesthesia because her colon was blocked w/dried feces. But that's the last bad bout of anything that she's had in months. So watch Lily closely for signs that she still might be blocked. (I know you will anyhow.)
