A Siberian Husky's coat is thicker than that of most other dog breeds, comprising two layers: a dense undercoat and a longer topcoat of short, straight guard hairs. It protects the dogs effectively against harsh Arctic winters, but the coat also reflects heat in the summer.
Interstitial lung disease associated with RA typically includes interstitial pneumonias and bronchiolitis (inflammation of the small air passages of the lungs called the bronchioles), as well as damage to alveoli. The symptoms of interstitial lung disease include shortness of breath, pain, and difficulty breathing.1,2. The formation of nodules in the lungs occurs in a small minority of patients with RA (less than 1%). RA nodules are more common in men than women. Typically, nodules are asymptomatic.
As mentioned before, RA could lead to muscle pain. One of possible reasons is because sometime the pain of RA can be painful enough to affect the muscle around the involved joint, causing muscle spasm. To work properly, your joints require muscles.Together, they are essential elements to support your movement. Some bouts may develop before the persistent signs of RA occur. 2  Symptoms unrelated to the joint problem could be noticed, too. 3  Even some can be more obvious before symptoms related to joint problem develop. 4  These include fever, weight loss, changes in appetite, anemia, and muscle pain.
