I'm sorry you experienced this. I've always had dogs - one of them died of liver disease. He was only 2years old.
There is nothing wrong with the food you gave him. Those are diseases that are often related to the breed, or to the in-breeding that goes on with some dogs. Good luck with this.
Find different opinions if you are not convinced with your vet.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
