My old man told me of his cousin's dog... it was just about to bite a skunk which made a den under the barn when the skunk sprayed directly into his mouth. The dog went through a hay field with his head sideways to the ground and his mouth open. he made it to the river where he began drinking and vomiting. Eat grass, drink water, vomit.

He came home three days later. Every time he smelled a skunk after that, he would go apeshit and bark incessantly until Dad's cousin killed the skunk.

Thank goodness he learned a lesson because there was a porcupine in the outhouse not long after and he wouldn't go near it.
