I live in the Netherlands and I really would like to know if there is a dog nutrition without the above mentioned ingredients.
3 years ago I have lost my Rottweiler Oscar because of liver cancer He was about 3 years old.
Now 2 days ago I have lost my Polski Owzwarek Nizinny named Muppet because he had leukemia. He was only 2 years and 9 month old.
I suspect the Pro Plan of causing the cancer.
Now I am desperately searching for a food without the above mentioned ingredients.
Can someone please help me?
