Oh no...Tate is worrying her Mama again, that little stinker. Sometimes, ringworm can cause hairloss; and while most ringworm always starts in a "ring" in human, that's less common in dogs - where "patches" can occur instead. Thyroid maybe? I'm pretty sure you tested that before though, right? Malabsorption can also cause hair loss, but you'd often see weight loss too...but maybe not right away. Any meds that she's on that could cause this?
I mean, it could be other skin issues as well - so I wonder if you should have skin scraping and fungal culture. Has her itching gotten worse at all?
Oh, Brooke, I feel so bad for you - I know you don't need another Tate issue on your hands to worry about
