I have a flea or problem at home, and I searched for flea repellent solutions I can make at home until stores opened (it was at night). I read that apple cider vinegar helped repel them. I used the 1:1 ratio and sprayed down my dog with it. This morning I went to take my dog out and with a horror, gagged at the site of diarrhea and vomit shot to every inch of my floor, and some on my door. I'm pretty sure ACV caused him to do that, since I know it can clean out one's system if drank. I assume that he started to nibble down on his coat or whatso and it got into his system. I'm very worried. All his food was vomited and diarrhea was everywhere (normal color). What can I do? Help.
