We noticed that when dogs have an upset tummy their vet often prescribes feeding simply chicken and rice for up to 3 days to see if that helps. For a dog owner making this food is rather onerous and so we have taken our irresistible 100% freeze dried chicken which is milled into powder and added lots of instant Italian rice plus some algae and vitamins and minerals so it is a complete food. We always recommend that if your dog has an upset tummy that you must visit your vet and ask them if it is ok to feed Thrive Kind & Gentle. If so then you simply pour some in a bowl, add enough boiling hot water to cover the dry mix and let it cool down.
