sorry, Jackie, I didn't see your post until just now!!
Another Update::
Well, Maddie is still doing good!

I had to return to the Vit A twice a day, because she was having a bit of a 'flare up'... But it stopped the flare up in its tracks and she started to look immediately better. I think we just weaned her off of too much, too soon. We're still doing the keto half a pill 3x a week (MWF), I don't know how much longer we'll have to do that. If she shows any further signs I'll have to up the baths again, which we're both hoping I don't have to do

but so far, not
She had a 'senior' wellness exam today, to check blood-work and everything. Since she's on the Vit A, and Vit A is a fat soluble vitamin the dermatologist told me to keep a close eye on her on the mild chance she could 'OD' so to speak.
Also, I always want a thorough checkup of everything else, especially her joints, teeth and her good eye. Apparently despite everything she looks REALLY good for her age

which is a HUGE relief to hear! But she has very minimal tatar, that of a 4-5 year old dog

and everything else looks good, and sounds good. I won't hear blood-work results until tomorrow, and *fingers crossed* the vet doesn't suspect anything will be off at all.

I sure hope the dermatologist is as thrilled with Maddie's progress as I am!
