Thank you for submitting your question regarding Spud. Addison's disease is not typically associated with hypothyroidism. However, when a dog develops one autoimmune disease, they can be more prone to developing another. Hypothyroidism cannot be diagnosed off of one low thyroid value though as this is not accurate. The thyroid levels can be artificially suppressed by stress or concurrent disease. Levels of thyroid stimulating hormone and free T4 by dialysis need to be evaluated in conjunction with thyroid hormone levels to make a diagnosis. I hope this information helps!
