Winnie is still a pathetic excuse for a corgi, so she is off to the vet this afternoon... Will update everyone on her prognosis when we get home!
Update: After a thorough examination they have determined that Winnie is... sick. She has a high white blood cell count, indicating an infection somewhere. She doesn't want to eat, so she might have a tummy infection, but she's also peeing a lot, so she might have a urinary tract infection. She got sent home with some general antibiotics, easy-on-the-tummy food, and a lower fever than yesterday.
