Responding because of earlier comment
Not 100% sure we can associate the problem with nutrivet as our dog is sick and on protopic - but she (exactly like the owner above has mentioned) has become flatulent and smelly with it ... ... so much so that from time to time immediately after feeding it's forcing us out of the same room as our dog
- occasionally thereafter she's tending towards diarrhoea and I'm having to wash her bum once in a while.
Will update if things change before ending the 12.5 kg!! pack.
