Having said that, since you have nothing to loose, I'd say there's can be no harm done in trying. If it were me, I'd go with a 24 drop p/1 liter mixture with a pinch of baking soda to stabilize ph(acidity). You can do a reading yourself or just simple taste test to check if its good and proceed with giving the animal small doses every 1/2 hour.
I've read that people have had good success with CDS in animals also mainly due to the taste.
PS. please keep us posted on how things go. This sounds like a very good case study.
