But even with this statement there are problems with its interpretation. In addition, testing a food for six months is not an adequate amount of time to determine if deficiencies or other long term effects may occur after feeding the product a year or more. Feeding instructions Feeding instructions or guidelines are included on most every bag and most cans of pet foods. These guidelines give the recommended amount to be fed based on growth level and weight. I would remind owners that these are very rough guidelines.
Every animal has a different level of activity, metabolism and ambient environmental temperature.
In addition breed, age, and other environmental stresses all impact daily requirements. I encourage you to use these guidelines as rough starting points. If your animal is thin or hungry feed it more often and in greater quantity. If your pet is obese feed it less. This is an area where common sense is much more important than science.
