Boxer Insane
I am still hoping somone on here can recommend a good dose of Vit C to start with.
Vitamin C is dosed to bowel tolerance. Too much will produce loose stools....diarrhea.
I originally posted the info you included in your post about the various items we used when my girl was battling d-mange. We started her off on chewable wafers which were 500mgs. Easily broken in 1/2 and she took 250mgs with breakfast and the other half at dinnertime.
To get her started I was using that one 500mg wafer split into 1/4's and gave over 2 days or 4 meals. That lasted about a week. After no issues with her stools I increased to 1/2 & 1/2. She stayed on that for about 6 years and multiple years after the d-mange was cleared up. She liked them and vet said they wouldn't hurt her.
As someone else mentioned, make sure these do not have anything added to them to make them more tasty like artificial sweeteners. The ones I had were orange flavored (naturally) and were quite strong/bitter tasting. I often ate one of her halves after broken in two.
