I have two six month old puppies, Kwazi and Ngozi. When I brought them home at nine weeks they were eating Fromm Puppy Gold. I asked my vet if I could switch them over to a raw diet since I had fed my adult dog Northwest Naturals,Chicken & Salmon and Turkey. He did very well on it and had very little "waste", which was an added plus for a 100lb dog. My boys were just diagnosed with Demodectic Mange and I researched and found out a weakened immune system causes dogs to get this. A dear friend told me that she thought the raw food may be the reason for the weakened immune systems in the the boys. Anyone have an opinion? The raw food does have added vitiamins,minerals and vegetables, it's not just raw "meat".
