Thanks so much for the info. She is doing great on the Thyro Tabs as well as the ACV application on the scruff of her neck as well as her feet (for urination issues). At 10 years old she is back to being a puppy again! She demands going for long morning walks and can't wait to go for a swim in the evening. Her nose is black again, tongue is pink and teeth are now white again (the kelp). She loves the re light therapy and sleeps soundly when the light is applied to the thyroid area. I will order a fan for her today. Thanks for the tips!
