The general causes of leg deformation are vitamin deficiency, overweight and congenital dysplasia. If the dog is a puppy, then leg deformation caused by vitamin and other micronutrient deficiencies are more common and require calcium and micronutrient supplementation. If the dog has severe obesity, then it may also be caused by compression due to excessive obesity, and if it is congenital dysplasia, then surgery is generally required for treatment.
