Day 28 DOCP

It seems the lower amount of prednisone (5mg/ day) is the right amount at this point.  It doesn't make Jack any less crazy, or less 'skiddy', but it keeps him together without the prednisone side effects.  Might be able to go lower still.
Throughout the pred increase, and subsequent decrease, his behavior didn't really change.  That is, his reticence to going up the hill, or anxiety about reaching a certain point and wanting to turn back.  He still does it.
Our hike this weekend was very like the rest.  He got up the trail a few hundred yards, and I had to put him on leash to make him continue.  Once he got into it 3 miles, or so, he was fine.

I decided to wait to his day 25 to get his electrolytes this time.  Very glad I did.  It came back:
NA151 (4.5 above range midpoint)
K 5.0   (.45 above range midpoint)
Ratio: 30 (2.5 below range midpoint).
DOCP dosage is constant at 2ml/50mg Percortin-V on day 28 this time.

Trending this data, it looks like both the Na and K numbers are increasing over the three months.  Sodium is consistently above the range midpoint, and K moving from below to above the range midpoint.
Na/K ratio is consistently declining.
Um... does this mean he's getting too much of a good thing, or that we're doing it right, and can just go to 28 days between injections?  I'm inclined to think we can back his dosage down 10%, and give them on day 28.
It seems a part of my brain is now permanently committed to assessing Jacks biochemical situation relative to behavior and what little analysis we have.
