In this brief segment, Dr. Conor Brady explains how selenium can be beneficial for canine health, particularly by modulating the immune system to address autoimmune thyroid disorders. He notes that improving selenium intake may support hypothyroid dogs by reducing autoimmunity rather than merely increasing iodine. He also warns that excessive selenium can damage a dog's hair and nails, leading to brittleness and nail fractures. The speaker emphasizes the need for appropriate selenium levels to reap benefits while avoiding toxicity.
