How to identify Labrador puppies? First of all, Labrador puppies generally have a small protrusion on the top of their heads (which disappears when they grow up). The mouth should not be long and slender, it should be short and thick; the ears are droopy. Pull the tips of the ears gently. , it is best to meet the corner of the eye on the other side; the part where the head and tail are removed should be in a square ratio; the coat colors are only black, yellow (dark yellow, light yellow), and chocolate, and the other colors are disqualifying or impure; black Labradors are generally all black, and those with white hair on the chest are disqualified. However, they are not impure. The tail should reach the hocks of the hind legs.
