Introduction to dog teeth:
The shape of dog teeth is various, and the length of the shape is also different, because there are many kinds of dogs, and there will be many hybrids and generations of hybrids during the period. So canine teeth are the most difficult to distinguish.
The variety of wolves is very pure, and the shape of spikes is similar, which is also what experts say. You can tell at a glance that there are spikes and fangs. Therefore, the best way to tell the true ear from the false ear is to look at the true ear and remember this shape, like this. It's all the shape conflict between dog teeth and true ears. Dog teeth are varied. We don't need to study what kind of dog it is.
Characteristics of dog teeth: dogs are not suitable for living alone in the wild. Naturally, dog teeth are short, thick and round after degeneration, which is not conducive to biting. It can't reach the slender and sharp blade feeling of spikes. The ratio of canine cusp to root almost exceeds 1 to 1.4.
Characteristics of cusp: straight, round and short? According to the structural characteristics of the cusp, the root characteristics of the canine cusp without blood horizontal stripes are obtained (some of them exist, but they are very rare, with thick stripes and irregular cracks, so it is impossible to completely judge whether it is true or false):
After the dog's teeth are often chewed and degenerated, the root of the dog becomes fragile, underdeveloped and deformed, and there are many dog teeth with uneven root, round belly, no smooth streamline feeling and acne on the root (congratulations on getting 100% dog teeth if this happens to the teeth you wear)? Therefore, the criterion of root is very important.
Speaking of which, I believe there are still many friends who can't tell the truth from the false. After all, they see less and learn more. If you don't know Spike and Dog's Tooth, you always know Wolf and Dog. The following bloodthirsty wolf tour is accompanied by a friend's graphic explanation:
The skulls of wolves and dogs are very different. Even dogs whose lineages are close to wolves, such as Demu and Husky, have many different skulls. Take adult wolves and German shepherds for example. Even the smallest adult wolf's skull will be more than 24 cm long, and it is rare for a German shepherd's skull to exceed this size. ?
It can be seen that wolves and dogs of the same size have bigger skulls than dogs, so their spikes are bigger than dogs' teeth. Moreover, wolves are carnivores, and they chew the flesh and blood of their prey for a long time, so dogs have developed teeth. The most obvious feature is that the teeth of wolves are longer than those of dogs, which is one of the reasons why the ratio of fangs to roots is about 1: 1.
Some "pointed teeth" sellers said: "The pointed teeth are very straight. If they are too long and bent, they will break easily. If the roots are long and thick, the teeth of this structure will be very strong. " You think wolves are prosperous wealth. Let's take a picture of a wolf and a dog directly below. You can't tell a wolf's teeth from a dog's. You should know about wolves and dogs. ?
Are these fangs suitable for biting people? Think about it. Short tooth tip+round blunt+straight tooth type = dog tooth. The following picture shows the skulls of two wolves, and the concave and convex bones at the tooth crowns are clearly visible. Friends try to draw the shape of the root of the tooth and see what the overall shape of the tooth is.
