Common Bone Disorders in Dogs

  • Arthritis: Arthritis is a common bone disorder in dogs, especially among older dogs. It causes inflammation and stiffness in the joints, making it difficult for them to move comfortably.
  • Hip Dysplasia: Hip dysplasia is a condition where the hip joint doesn’t develop properly, leading to pain and difficulty in walking. It is prevalent in certain breeds and can be hereditary.
  • Osteosarcoma: Osteosarcoma is a form of bone cancer that commonly affects dogs. It usually occurs in the long bones of the legs and can be quite aggressive, requiring prompt medical attention.
  • Intervertebral Disc Disease: This disorder affects the discs located between the vertebrae in a dog’s spine. When these discs degenerate or become herniated, it can cause pain, paralysis, and difficulty with movement.
  • Patellar Luxation: Patellar luxation is when the kneecap becomes dislocated from its normal position. It can cause lameness or limping and may require surgery to correct.
  • Fractures: Dogs can experience fractures from falls, accidents, or trauma. Fractures may vary in severity, but they should always be treated by a veterinarian to ensure proper healing.
