I think she has listeriosis. Often found in the soil. Hard to cure, but i started her on an antibiotic that is supposed to be effective against it. Giving her fluids by bottle regularly, and vitamins, electrolytes. If i had IV fluids, i would give her those too. If i took her to the vet, i am sure the bill would exceed what i could ever get for her. And no guarantee on the outcome.Did she get too hot at the swap or what do you think is going on?
