Yah! That's cheap and easy to treat! I have more experience than I'd like with hypothyroidism! Preacher had it as do Earle and Chum. You may find Sasha wants to eat a bit more once she's feeling better. Just limit her fat intake. Earle gets baby carrots as treats and green beans added to his kibble so he doesn't think I'm starving him. With every one of my hypothryoid dogs, I noticed improvement in their energy levels, mood ect within a week of starting the meds!

I have a hyperthyroid cat and one of my vet's major concern with treating the hyperthyroidism is that it may negatively impact Beau's kidneys. The hyperthyroidism forces everything into overdrive, including his kidneys. Beau's ancient so his kidney function is marginal. I would assume that the opposite is also true--hypothyroidism causes less of everything, so the kidneys aren't working as effectively and will work better once the thyroid is regulated.

I hope Sasha is feeling better soon!
