How do you tell whether a Shiba Inu puppy is pure or not? The head of a Shiba Inu puppy should be larger, with the back of the head moderately raised, and the forehead should be moderately wide with a little arc. When choosing a puppy, choose one with a nose bridge that is neither too deep nor too shallow, and choose small, triangular ears. The eyes should be slightly triangular, the lower eyelid should be close to a straight line, the eye color should be close to black, and the darker the lip color, the better.

The head of a Shiba Inu puppy is preferably larger, and the back of the head should also be moderately raised. The forehead should be moderately wide, with a little arc when it is a puppy. It will be better when it grows up, but if it is too prominent, it will not be good. The bridge of a puppy's nose will be relatively deep when it is a puppy. When considering this, you should pay attention to choosing a puppy whose nose bridge is neither too deep nor too shallow.

Some puppies’ ears cannot stand up even 40 to 50 days after birth. If the ears do not stand up, use your fingers to lift the puppies' ears up and observe their ear shape, thickness, ear position, forward inclination, etc. When choosing, look for small ones with a triangular shape. Don’t choose ones with round ears or those that look like bamboo leaves. In addition, the so-called small size should also be in proportion to the head. The one with appropriate thickness, slightly leaning forward, and the right distance between the ears should be selected.

The eyes should be slightly triangular, the lower eyelid should be close to a straight line, and the upper eyelid should have a larger arc starting one-third from the head of the eye. This eye shape is the correct eye shape. Puppies don't grow up to this extent. It is best for puppies to have round eyes and no eye droppings. When they grow up, the best color of their eyes is dark brown. However, when puppies are young, the color of their eyes should be close to black. Avoid choosing those with light eyes.

The muzzle should be thick, round and tightly closed, and the nose should be black and shiny. Don't pick a dog with a droopy upper lip, as if you can't see the lower jaw. The thicker the lip color, the better. Light color is not good.

There should be twenty-eight deciduous teeth together. There are six upper and lower incisors, two canine teeth, and six molars. Make sure the teeth are straight. Even if some puppies have all their deciduous teeth, they may not be complete when they are replaced with permanent teeth. This situation can only be regarded as bad luck.

In terms of occlusion, a correct occlusion is when the lower incisors are zigzag-like with the upper incisors on the inside.
