Что будет, если кормить собаку или кошку натуралкой и дополнять сухим кормом и наоборот

Is it possible to feed the dog natural and add a little dry food and vice versa? Very often I am asked to answer these types of questions. These are the questions asked by pet owners who are feeding their animals dry food and who understand that natural feeding is certainly better. But due to the fact that there is no possibility, mainly due to lack of time, to provide their animal with constant natural feeding, they give their pet, in addition to dry food, and something else from natural products. To what extent this is allowed and how it relates to, see the video.
