Why did the dog start shedding in autumn? - briefly
Autumn triggers dogs' seasonal shedding due to changes in daylight and temperature, which disrupt their hormonal balance and cause them to lose their summer coat.
Why did the dog start shedding in autumn? - in detail
The onset of shedding in dogs during autumn is a natural response to changes in daylight and temperature, primarily driven by the hormonal system. As days grow shorter and nights longer, the decreased sunlight exposure triggers a reduction in melatonin production, which regulates sleep-wake cycles and also influences hair growth patterns. This shift in hormone levels prompts the follicles to enter a resting phase, causing existing fur to loosen and fall out.
Moreover, the cooler temperatures of autumn stimulate the production of new fur, preparing the dog for winter's colder conditions. The old coat, which is designed for warmer weather, sheds to make way for a thicker, more insulating undercoat that will better protect the dog in the coming months. This seasonal molting process ensures that dogs maintain optimal body temperature and comfort throughout the year.
Additionally, the change in diet and activity levels during autumn can contribute to shedding. Dogs may reduce their outdoor activities as temperatures drop, leading to less wear and tear on their coats. Consequently, the old fur that would have been naturally shed through movement and grooming remains until it is manually removed or falls out due to hormonal cues.
In summary, the combination of decreased daylight, cooler temperatures, and changes in activity levels triggers the dog's natural shedding process in autumn, preparing them for the upcoming winter season.
