All I can tell you is not all oil is the same. And dogs, like people, have individual reactions to THC. I think a "crash test dummy" is needed here. Have you tried ingest some of that oil yourself? I'd try the same amount that you gave her. If I feel it at all, I'd know that it's way too strong for her. If I get little of no effect, that would tell me that she is very sensitive to THC. In which case you might be able to break that amount into 3, or more doses throughout the day.
