Apple Flea In A Bottle. Yes, apple cider vinegar works to repel fleas on dogs. Moreover, what can i use to keep fleas from biting me?
While apple cider vinegar does not kill fleas, it may repel them because fleas dislike its smell and taste. Repeat every couple days to maintain the effectiveness. (you can find empty spray bottles at dollar stores or grocery stores.) spray your pet daily with the vinegar spray.
