we see that all the dogs have black nose ,i want to know whats the reason for it?,,,,,

Hello Madussaji
actually i don't know the answer of this question but i am eager to know the answer of this question, by the way i think its something related with heridity.

All the dogs do have not black noses. Some dogs have pink noses, or even white. Some dog's noses are black to keep their nose from getting a sunburn.

Dogs have most likely developed black noses as a protection against
Sunburn. While the rest of the dog's body is protected by furs,
Light-coloured noses are exposed to the full force of the sun's rays.It is genetic factor.

However,not all dogs have noses black some also have,pink,red,brown just because of the genetic factor associated with it.

hi esha,
i think that its some thing to do with there smelling powers,
lets wait and see whats the correct reason

you can find answer to this question in some biology book,you can try the official website of national geography also

the dogs nose are black for their ability to sense heat,because its black in nature the dogs nose can change even an minute change in the temperature

well i was also not knowing this but seeing the replies i can guess why it is so .....
thanks for the question

hi
Hair and skin both human and animal contain melanin which is what gives color to them.
As we and they start to age we lose some of this substance.That is why hair turns gray,lack of melanin.
I know for fact this is the case with hair and I'm pretty sure it is true for dogs nose.

Actually i am not know this answer but i also wants answer to this question.....

While a majority of dogs have black noses, not all do. The noses of
dogs such as vizslas and weimaraners match their coat colours - red
and silver, respectively - and it is not unusual for puppies of any
breed to start out with pink noses that then darken as the animal
matures. I had a Shetland sheepdog that retained pink on the insides
of her nostrils for the whole of her life.

Dogs have most likely developed black noses as a protection against
sunburn. While the rest of the dog's body is protected by fur,
light-coloured noses are exposed to the full force of the sun's rays.
Pink-nosed dogs, hairless breeds and dogs with very thin hair on their
ears need to be protected with sunscreen when they go out of doors,
just as humans sometimes do, or they risk the same

No, not all dogs have black noses. Some dogs have pink noses, or even white. Some dog's noses are black to keep their nose from getting a sunburn

the colour of the dogs nose are different.for example the colour of human body differ from each other it depend upon the climatic condition like this only the colour of the dogs nose differ.

all the dogs dont have black noses .. it depends on their own hereditary

No my friend this is not true that all dogs have black noses. Some dogs have pink noses, or even white. And those dogs who have black noses they keep their nose from getting a sunburn.

what a question i liked your query and got a faded idea of dog having black noses........ thanks for this question

Pigmentation in a dog’s nose is determined by genetic factors, the dog’s nose may be black, pink, liver colored, or self colored (same color as coat). But, what does it mean if your dog’s nose changes color? If your dog’s nose is turning pink, specifically turning from black to pink, there could be many causes for the loss of pigmentation.

dear freind this is the natural thing.......and we know that for understanding the nature thinking is not the limit of mans......

i think dogs have black noses because we humans mostly have white noses...

what lame answers! if it was for sunburn why arent white peoples noses black?

God has created them like that nobody can change it

The color of dog's nose can be black,pink,liver colored,or the same as your dog's fur..Nose color is determined by genetics..some noses faded during colder months and return to their normal color during summer months..

nose pigmentation is important to protect the dogs from sunburn and skin cancer.its also quite useful in identifying a dog's actual color.
