Do purebred Labrador Retrievers have black noses?

Not necessarily! While many purebred Labrador Retrievers have black noses, it's not a guarantee.

Here's why:

* Color Genetics: Labradors come in three colors: black, yellow, and chocolate. The color of the nose is directly linked to the coat color.

* Black Labs: Black Labs almost always have black noses.

* Yellow Labs: Yellow Labs can have either black or brown noses. The darker the yellow coat, the more likely they are to have a black nose.

* Chocolate Labs: Chocolate Labs typically have brown noses.

Important Note: Even within a single litter of puppies, nose color can vary. It's not always predictable.
