What could a black lab be mixed with if it starts to get brown fur as puppy?

It's not uncommon for black Labrador puppies to have some brown or tan fur, especially on their legs and muzzle. This is often due to a combination of genetics and the puppy's age.

Here's why you might see brown fur on a black lab puppy:

* Incomplete pigmentation: Black Labs can carry recessive genes for other colors like chocolate or yellow. These genes may not be expressed fully at first but become more apparent as the puppy grows.

* "Fading" or "Tan Points": Some black Labs have what's called "tan points," where they develop lighter fur on their legs, muzzle, and chest. This is a variation within the breed standard.

* Puppy coat: Puppies often have a slightly different coat color than their adult coat. They may shed their puppy coat, revealing a darker or lighter color underneath.

It's unlikely that the black lab is mixed with another breed just because it has some brown fur. However, if you're concerned about the puppy's coat, it's always a good idea to talk to your veterinarian or a reputable breeder. They can help you determine if the brown fur is a normal variation or a sign of something else.

Here's a general guide to coat color in Labrador Retrievers:

* Black: Solid black coat

* Chocolate: Solid brown coat

* Yellow: Can range from light cream to fox red

Remember: It's important to avoid judging a puppy based solely on its coat color. Every Labrador Retriever, regardless of color, has the potential to be a loving and loyal companion.
