Dogs' ears consist of cartilage and skin. In the dog's ear cutting operation, the outer edge of the ear is cut off, which makes the ear change to some extent. The cartilage in the dog's ear will also change, leading to curling. In addition, the size and shape of the dog's ears will also affect the degree of curl.

The structure of dog ears affects the shape and degree of curl. For example, some dogs' ears will show the shape of "West Indies Hook", which is caused by the bending angle of ears and the structure of cartilage. Other dogs' ears will be curly, which may also be caused by the shape characteristics of their ears.

2. Genetic inheritance is also one of the reasons.

Dogs' genes also affect the degree of ear curl. Some breeds of dogs are born with curly ears, such as Boston terrier and cocker spaniel. This is caused by genetic factors. These dogs will have curly ears even if they don't have ear surgery.

On the contrary, some dog breeds have upright ears, and they will not be cocked up without surgery. Therefore, the degree of dog's ear curl is also closely related to heredity.

3. The technique of ear surgery will also affect the degree of curl.

Although the structure and genetic factors of dog's ears are the main factors to determine the degree of curl, the technology of ear surgery will also have an impact on the degree of curl of dog's ears. If we do ear surgery, not only cut off the outer edge, but also take a triangular area above and below the ear, the dog's ear will curl more obviously.

This is because in this way, the rest of the ear bears more weight and increases the possibility of curling. Therefore, in order to prevent the dog's ears from sticking up too obviously, we should pay more attention to the technique of ear surgery.

4. Different breeds of dogs have different degrees of ear curl.

There are also great differences in the degree of ear curl among different breeds of dogs. Some breeds of dogs have naturally curly ears, and the degree of curling may be more obvious after ear surgery. However, some breeds of dogs have upright ears, and their ears will not become too warped after surgery.

Therefore, for different breeds of dogs, ear surgery should be carried out according to their own characteristics, and it cannot be generalized. Moreover, before ear surgery, it is better to consult a professional veterinarian to understand the ear structure characteristics of dogs, so as to perform the surgery more accurately and avoid unnecessary risks.
