Explanation:

A dog's hair is mainly made up of proteins especially keratin. Therefore for a dog's hair coat to be healthy, it needs protein in its diet. The glossy texture of the coat come from the skin secreting sebum – mainly made of lipids – that prevents the skin from drying out. This is why the dog's food should also contain lipids such as omega-3 and omega-6 fatty acids.

Proteins and lipids are also the main components of the bi-lipid cell membranes of cells that make up the dog. Also, proteins make up muscles because they are the main component of the actin and myosin fibers that contract for muscle to do work.
