Choc Lab kidney/liver failure

Question
My 7 year old lab one fine and the next day he wasnt eating and acted like he was sick, I took him to the vet and he was diagnosed with liver and kidney failure. All of his blood work was bad and the vet said he had diabetes. How does a healthy dog go that quickly?

Answer
Unfortunately likely the damage started a long time ago, but never showed up until too late.  That is often how organ damage goes. Starting to do blood work at that age often turns up problems in time for many dogs, but would have been too late to help yours.  I am sorry it happened.
