Why does your Lab’s nose change color?

To be perfectly honest, experts still seem to be a little baffled by this occurrence; and to their knowledge, nobody knows. In some cases, it can be due to an irritation, but in other cases the nose would look agitated and the dog might scratch it. It is known that in some cases the colour will return, and in others it will come and go. If this is the case, you should determine if it happens at the time of moulting. A mineral or vitamin supplement may be helpful, so you could discuss this with your vet. For dogs that have pink noses, the possibility of getting sunburn is really very high! Be sure to apply some sun-screen if the weather is hot and in particular if your dog stays outdoors. It has been known in some cases for dogs with pink noses to be tattooed to restore the colour!
