on small animal care and nutrition. She's done a lot of looking into using Vit C by the looks of it, quite scary to think of some of the vet bills we accrue that can be fixed by something as simple as Vit C. Hell I wish my old boy with HD was still alive, apparently CURABLE with Vit C in mega doses! I'd be experimenting with him LOL.
She also gives the handy tip of putting a copper pipe in dogs water (it's amazing how the old farmers knew things, apparently they used to grate slivers of copper into the working dogs food) and that is enough to ward off most of the fungus/parasitic probs.
Of course this is all applicable for horses too, it's just this is a more up to date book so has some new stuff in it

Best thing is like she says in the back of the book, if you misdiagnose you're not going to kill them with the treatments!
