What illness causes dogs eyes to be yellow and have blood discharge before dying?

Dogs eyes become yellow,dog urinate with blood,dog vomit blood and dogs feces with blood .
the dog has complete vaccine shots.
my dog already died yesterday. I am just puzzled to what caused her death. She is a rottweiler,1 year and 2 months old. Suddenly stopped eating for a day then,she has blood with her body waste. She died just after a day and a half of not eating and losing body fluids and blood.

• How many dogs are you allowed to have before you need a kennel license?
• Why is my dog too much shy or submissive with other dogs?
