After shearing, without follicle damage, a dog’s new hair generally grows back within a month, with a length of about one to two centimeters. The hair growth rate varies among different dog breeds.

Hair Growth Rates in Different Breeds
- Short-haired dogs: Generally, short-haired dogs have a relatively faster hair growth rate, such as Poodles, Bichon Frises, and French Bulldogs.
- Long-haired dogs: Long-haired dogs like Golden Retrievers and Border Collies have a relatively slower hair growth rate.
The Impact of Health Conditions on Hair Growth
If a dog is in good health and well-nourished, the hair growth rate will be relatively fast. Conversely, if a dog suffers from malnutrition or a skin disease, the hair growth rate may be slower.
The Influence of Environmental Factors on Hair Growth
A dog’s skin quality and hair growth rate may also be affected if it is in harsh environments with excessive temperatures, high humidity, or strong ultraviolet (UV) rays after shearing.
