There are natural agents called DMOAs or disease-modifying osteoarthritis agents that help dogs with osteoarthritis by improve the function of bone cartilage or fluid (synovial fluid, a fluid that lubricates the joints). These products include glucosamine (a substance the is naturally found in a dogs body) and Chondroitin sulfate (CS). Studies are inconsistent, with some showing improvement in relieving some arthritis symptoms in humans. Both are found in dog foods that promote joint health, although there are no studies that support their use at levels in food. There are also other ingredients that have some support for use.
What is the prognosis for difficulty breathing?
Unfortunately, the prognosis for survival from difficulty breathing varies with what the underling problem is, financial constraints (which may limit treatment options), and severity of the disease. In the case of trauma or bleeding into the lungs from mouse and rat poison, the prognosis is better, as long as prompt, aggressive therapy and treatment can be initiated. With certain diseases like pneumonia, the prognosis is fair with treatment but with cancer, the prognosis is poor to grave.
