There are several reasons why a dog's fur may turn black. It could be due to natural aging, genetics, skin infections, or hormonal imbalances. It is best to consult with a veterinarian to determine the exact cause and appropriate treatment for your dog.
some do
White, Black and Brown
To have offspring with black fur, both parent dogs must carry the gene for black fur. This gene is usually dominant, meaning that if at least one parent carries it, there's a high chance the offspring will have black fur. If both parents have black fur, then their offspring will also have black fur.
all dogs have fur
there is really no difference.....most people say dog hair is what it is called when it falls off the dog and fur when it is on the dog...dogs with short fur/hair get less fleas then dogs with long fur/hair.... dogs also with white or light fur get more fleas then dogs with dark or black fur...
they can not be born pink but you can dye their fur pink but iit burns its fur and skin (you should not dye your dogs hair)
Why don't white people with dark hair have black skin?
Dogs get fleas in their fur. Chuck Norris gets black bears in his beard.
The animal that is born black before turning white is the Arctic fox. Their fur is dark when they are born, but it gradually changes to white as they mature to help them blend in with their snowy environment.
They have tails, paws and fur. But they also have black and white vision.
This could be a normal pigmentation change in some dogs, particularly those with darker fur. However, if there are sudden changes in the nipples or skin such as redness, swelling, discharge, or irritation, it is best to have a veterinarian examine the dog to rule out any underlying health concerns such as infections or hormonal imbalances.
It's probably just because he's getting older, and change of the fur color is normal for older dogs because their fur changes color. Hope this answered your question.
