How does dog and cat hair grow? Hair begins growth within a little pocket called a follicle where it is nourished by proteins and other materials in the blood. Blood also carries hormones, such as epidermal growth factor, that determine the growing, resting, regressing, and shedding phases. ![]() Hormones that control hair growth are influenced by sunlight and temperature, so that many pets have major growing and shedding cycles each spring and fall. With more pets kept indoors in a controlled climate, marked growing and shedding cycles are less frequent, and many pets appear to shed more evenly throughout the year.

Poodles and Shih Tzus are good examples of dogs with constantly growing hair. Although these pets don't shed, their coats require care, usually clipping every 4- 6 weeks. Hair growth can be compared to leaf growth. Trees have new leaf growth in the spring, then during the summer leaves stay active but are no longer increasing in number. In the fall, leaves die. In late fall, they fall from the tree.

For example, hair over the back and hips grows more slowly than hair on the chest. ![]() ![]() The rate at which hair grows is influenced by hormones and by blood supply. A good blood supply brings nutrients and a normal concentration of hormones so that the area experiences healthy hair growth. Areas with a poor blood supply do not have healthy hair growth.
