Depending on the severity of your dogs illness, a full blood panel may be recommended to determine the level of
dehydration in your dog (their pack - cell volume, or PCV), to check for an
elevated white blood cell count (that may indicate an infection
as the cause of illness),
as well
as full chemistries to check on the status of the bodies major organs (liver,» kidneys, etc) and make sure they are all functioning correctly.
