I'm so sorry Lulu isn't feeling well. She could be very sore from the diarrhea, and that may be what is making her cry. Are her gums sticky to the touch? I usually check that to test for dehydration and also pull the skin on the back of the neck to see if it goes back quickly when released.
The lethargy concerns me. She's been through a lot, and that could be the cause, but she's so young to be lethargic. I hope she starts to improve and gets well quickly. |
