GOod morning. Did he ingest the entire thing, or did you grab it back from him? Honestly, I feel he is not showing any signs of distress or changes in behavior, I would think he is ok. I would definitely keep an eye on him and contact the vet right away if anything changes. You might also want to call poison control if you’re still concerned, to get a better, more definitive answer about the alcohol swab. Good luck! Hope everything is ok??
