They might, but those yellow numbers right now are from bouncing (
see 2nd post in this thread for an explanation.) Her green cycle yesterday triggered a bounce to the yellow numbers today.
When you're dosing with Lantus, you're most interested in answering the question "how low does this dose make Daisy's blood sugar go?" Right now you know that the 1.25u can get her under 89, so that puts her in for a reduction to 1.0u according to the SLGS guidelines.
If you want to try to get her more in greens, you'd want to switch to following the Tight Reg Protocol guidelines. I'm sorry I don't recall why you're using SLGS - I'm not seeing that she eats dry food so perhaps it's just a choice? You test enough for Tight Reg. With Tight Reg, you wouldn't reduce until she goes under 50 on a human meter. That would mean she would stay at the 1.25u.
Hope some of that is helpful for your dosing question.
