feeding medicine

Feeding sounds odd in that context.

I usually hear "giving" in that context. Administering can be used but sounds stuffy.

Giving him medicine, or dosing him with medicine.

In North America, dosing is most often used when talking about farm animals.

I'm not sure how/why it evolved in that way, but if you told someone in my hometown that you were measuring a dose, they'd think you were preparing medication for a goat/cow/pig/horse etc - and dosing is giving that medication to the animal.

In Britain, it is mainly humans. It is very often used in connection with a temporary condition, and when a short course of medication is being talked about - I had backache/hay fever/a cold/toothache so I dosed myself with painkillers/antihistamines/Vitamin C/whisky. We dose children and yes, animals.

I've heard of feeding someone medicine, but only when the doses were very frequent. If that isn't the case, I suggest you don't use it.

Thanks to all of you.
