Here's what you can do to find out:
* Contact the breeder: If you got your puppy from a reputable breeder, they should have documentation proving the parents' lineage and breed.
* DNA testing: A dog DNA test can determine the exact breed composition of your puppy. This is the most accurate way to know for sure.
* Consult a veterinarian: Your veterinarian may be able to assess your puppy's physical characteristics and compare them to Labrador standards.
Important note: Even if your puppy is a mixed breed, that doesn't make them any less special or lovable! All dogs deserve loving homes regardless of their breed.
