That is a familiar computer term.
However, the same cannot be said of the low grade dog foods that are offered by many companies.
Major Corporations in the Food industry either sell or use in their own dog food companies food that would not be permitted to be sold to humans.
This includes waste from processing plants like oils and unpalatable meat products.
When this is mixed together the oil and grease previously used for frying food coats the meat and the cereal products put in as fillers to bulk up the end product.
That could be by as much as five or six years. So what is the answer ?
There are now a number of companies producing dog food that really is of the same grade as food produced for us.
Things to look for on a packet are the fat content, the cereal percentage,what preservatives are used.
It makes sense not to feed it to your dog.
