If a deformed dog is born, you should contact your veterinarian immediately for a thorough examination. A veterinarian can evaluate the puppy's health, determine the nature and cause of the deformity, and provide appropriate treatment recommendations. In some cases, malformations may be caused by genetic factors, while in other cases, they may be caused by environmental factors, malnutrition, or infection.

Depending on the severity and type of deformity, treatment options may include medication, surgery, physical therapy, or supportive care. In some cases, euthanasia may need to be considered if the deformity is severely affecting the dog's quality of life.
