When the Eukanuba manufacturing plant at Leipsic, Ohio was owned by P&G, it was P&G's largest dog food plant. Metal detectors are used to detect foreign objects that may have fallen in. Bags are marked by numbers to indicate the day and the hour the food was made using the DD/MM/YYYY format, so that the bags can be traced in case of a recall.
The ingredients in Eukanuba products contain both animal and animal by-products, which are the non-rendered lungs, spleen, kidneys, brain, livers, blood, bone, partially de-fatted low temperature fatty tissue, and stomachs and intestines freed of their contents. By-products do not include hair, horns, teeth and hooves. Most of the ingredients come from the United States, but a limited amount of nutritional supplements are imported from countries such as China.
