Canine arthritis is a common condition in dogs, characterized by inflammation and pain in the joints. It can result from aging, injury, or underlying health issues, leading to decreased mobility and discomfort. Symptoms may include limping, stiffness, and difficulty in performing everyday activities like climbing stairs or playing. There are different types of canine arthritis, including osteoarthritis and rheumatoid arthritis. Diagnosis typically involves a veterinary examination and may include X-rays to assess joint health. Treatment options often include medications, weight management, and physical therapy to help improve the dog's quality of life.
