Jacey started thyroid pills 9 August: .4 mg morning and night. I had both dogs at the vet last week (for bordatella vaccinations) and had blood drawn from Jacey to check the thyroid levels: barely any change at all, which is what I expected. She hasn't lost any weight on the pills (although weight loss is common, mostly because dogs needing thyroxine usually have put on weight--and she did); and the situation with the hair on her back legs wasn't any better.
So the vet wants to go up 50% on her dose. She'll be getting .4 mg in the morning, but .8 mg at night. I have a supply of .8 mg pills for her and Sam, so this way I don't have to go get pills with a different dosage level. (Sam currently gets .8 mg in the morning, 1.2 mg at night.) About Thanksgiving, I need to remember to compare her condition now with her condition then to see if I think another vet visit and blood test is warranted. (The blood work is $40; I'd like to not have to do it again.)
