Home: It's the structure of the dog's head. Generally speaking, the front page of a better Samoyed dog is triangular, with a naturally prominent nose, a flat chin, uniform eyes, dignified eyes and a naturally black nose slightly upturned!
Hair quantity: just look at the dog's hair to see if it is smooth, natural and shiny. The hair of sled dogs is drooping, that is, the hair on the back is hard and upright, and the hair on the abdomen is soft and smooth.
Bone mass: This is a very vague concept. Generally, only owners who have dogs will look at dogs like this, but it is also the best of these methods, that is, touching the whole bone of the puppy with their hands. Samoan dogs have slightly longer limbs, thicker bones at the root of legs, short ribs on both sides and long ribs in the middle, and thick and flat shoulder blades, which are tough and powerful.
The above is personal experience, for reference only. Good luck!
