Of corse it is hard to survive for some bears because they live in cold climates like the polar bear this bear lives in Antarctica so this bear does get thicker fur but some just hibernate and get ALOT of fat stored up
Bears do not change their fur for the winter.
Koalas are not bears. Yes, they have fur.Koalas from the southern parts of Australia have longer, thicker fur than those found in the northern areas.yes
probably winter or spring
there fur and dens.
They have fur to stay warm in the winter, but it also keeps them warm in the summer!
the polar bears fur sits down flat in summer in winter their fur is all fluffed up
Because the ladies like the colour and it will not get war so they have to get really fat that they can live in the winter.
Most (not all) dogs develop a thicker undercoat of fur to help insulate them.
It helps them shed the old fur so that new and thicker fur can help them stay warm. They usually molt during winter.
They shead their fur in the summer, and in the winter the hare gets thicker and more pufted up, then with the air in-betwen the fur it becomes an insulator.
Polar bears have blubber, which is like extra fat, under their fur and that helps to keep them warm during the winter. They also grow out their winter fur coats to keep themselves warm during the winter.
Their fur gets longer and thicker, giving them warmth during winter and during the warm seasons, they shed fur and start growing them in fall so they can have it fully grown by winter.
