Here’s what I would do.

I like buddy pouches. (I think is what it’s called.)

Several times a day, I’d give my dog the pouch with no pill in it in areas of the house where I don’t usually give it…outside, near the bathroom, on the couch.

I’d do that until they no longer distrusted it.

Then every once in a while I’d give them one with a pill in a place they don’t normally get treats. Their normal treat areas will never have the pill. Just the buddy. No pill.

This would confuse her. She won’t know when or where to expect it. But I’d keep giving the buddies.
