Strictly, we don't. Rather, we require amino acids, which are the components that proteins are built from. Particularly, we need essential amino acids, of which there are different numbers for different animals. For humans, there are eight truly essential amino acids, two more which are truly essential only in infancy, and eight conditionally essential amino acids. Aside from these dietary requirements, animals can survive without any other protein intake. However, protein is a very convenient source of food-energy.

How is protein lost from animals?
Except for the protein that is used by the animal, protein can be lost in several ways. For example, if the animal has a problem with digestion or absorption, protein can be lost via the faeces. Protein can also be lost into the abdomen, and animals with kidney malfunction can lose protein via urine (eg. a protein losing nephropathy).
Why do animals require nitrogen?
