It is a simple natural response to keep themselves warm.
Dogs grow thicker winter coats to keep warmer in winter. The signal for dogs to grow their winter coats is the length of daylight each day; as it declines, the dog's body reacts by growing a thicker coat.
they grow a thicker coat during the winter because its so cold then loss it in the summer so they don't over heat

The actuall patern would not change, but in winter it would have a thick coat, autumn losing the coat, summer normal coat (thin), spring, begining to grow the thicker coat again.

Thicker hair is needed as a protection against the extreme cold of winter. The thick coat is shed in summer as the weather can be very warm.
In the US, animals like squirrels, rabbits, deer, and birds have adaptations to survive the winter. They may grow thicker fur or feathers, store food for winter months, change their diet, or go into hibernation to conserve energy during the cold season. Some animals migrate to warmer areas during winter to avoid harsh conditions.
Winter White Russian hamsters are well known for changing their coat in winter. As the name suggests, they go white in winter (it's used as camouflage against the snow in the wild) and during summer they go brown (to blend in with their background after the snow has melted).
Animals grow thicker fur in winter as an adaptation to colder temperatures. This process, known as "seasonal pelage," involves the growth of larger, denser hair follicles that provide better insulation against the cold. The thicker fur traps air, creating a layer of warmth, while also reducing heat loss. This adaptation helps animals maintain their body temperature and survive in harsh winter conditions.
