I have a 2 pound chihuahua she hasnt been eating, she is drinking very little and is currently running a fever. I am very sad i cant not do anything to help her, she seems so misrable. I have took her to the emergency vet, which they have ran blood work and gave her fluids through a IV and they still have not found, why my baby is soo sick. :( she stayed over night and i took her to the local vet the following day and they noticed a fever of 100.3 but did not give me any answers.. please, i hope someone could help or give me some kind of answer.
