"Zappa loves his food and most important it is very healthy for him! I just wanted to give an update on Zappa. In the past we gave Rockster once in a while when we did not had time to cook. Recently Zappa was quite ill. For weeks he had stomach problems and diarrhea. He even had a gastroscopy, was put on severe antibiotics and acid tablets. It helped a bit but he still had very bad stools. We decided to put him permanently on Rockster. In a week we saw rapid change. His intestines work again as they should. We have again a happy and healthy dog. Rockster you rock!"
