just brush your teeth well, as well as your tongue and gums.
and drink lot of water, and stop eating oily meat stuff and start eating healthy grass

gogiking, thanks for your contribution. unfortunately just a normal brushing for about 5-4times per day will not stop this odour. Your recommendation could be helpful to someone is has temporal bad breath but, it will not work for someone suffering from chronic bad breath. This is because the VSC (volatile sulphur compound) responsible for production of this odour hides beneath the tongue & stomach.
Yes, eating unprocessed food such as vegetable,fruit...ecc could help eliminate these bacteria's since, most naturally-made food contain's alkaline.
