Did that link I gave you on meds not give the direction on dosage?
We need to get in touch with @casportpony
Yes it did!! Thank you for pointing that out. I saw the photo but no typing to go with it. I didn't realize the dosage was on the photo.
Should I separate her from the others or dump out their pool so that this is their only source of water?
Is that the picture that says the dose is 2.5 tablespoons? If so, that is wrong, and I contacted the mfg about it. If it's the package I think it is, there are about 18 tablespoons of powder, and the 800mg dose would be 1.5 tablespoons, not 2.5 tablespoons. Please confirm which package you have.
