Out of all the dog foods that I have tried for my rottweilers, I found Venky's Best in Show the best. My recent Rott, 9 months old male is completely on Venky's Betsy in Show and has been fantastic in terms of his weight, stools, strength, skin and coat. To my first Rott I used to give Hills Science plan but that resulted into foul smelling stool. When I started RC for him, he didn't like that food somehow. Finally I settled down on Pedigree Professional Range and that was again a very good dog food. But out of all this I recommend Venky's Betsy in Show as it has given the best results on my dogs. It is economical too as compared to RC. It is slighly expensive than Pedigree professional range but quality is far better.
