Liver is the only organ that has the ability to regenerate, but when it comes to a dog of Nadi's age, her chances are decreased. However, who knows, labs can be wrong too.
Poor dog, it breaks my heart to see that look on her face as she can't understand what's going on, but you have to do this, it's in her best interest.
Fingers crossed.
