Montego not nutrition!

Montego puppy large breed. Recently bought 2 x German Shephard pups, now almost 5mnths old. Started them off on this. We almost lost both of them due to intestinal infections. The vet bill aside, the money spent on the food aside, where is your sense of care towards animals when this complaint, along with others like skin issues etc, are all over social media. Please dog *****s, stay away.
