I tried giving my dogs (9 months, 10 and 12 years old, respectively) ACV in their food. I only gave them 1 tsp. per day. After two days, they all started hacking, and kept my husband and I awake all night. I stopped the ACV, gave them some cold pressed barley pills (three each), and they have slept through the night since. The hacking completely resolved in a day. A friend told me that ACV actually ate through the stomach of another friend's dog and killed him. I am going to try the ACV TOPICALLY and diluted for my 9 month old's ringworm, but would caution anyone against giving it orally to any animal.
Apple Cider Vinegar
My 5 week old kitten has a horrible case of ringworm and I have been using Lotrimin ultra on him and it seemed to be slowly working but i am afraid he was licking it off of a spot on his leg and i don't want him to get sick so I tried dabbing on apple cider vinegar. It apparently stung him so badly and he was so upset that he cried and vomited 5 times, poor baby. I was very excited to try it as I know vinegar won't kill him but I don't think I have the heart to put it on him again. I feel horrible that I put the poor little guy through that. I plan to cross my fingers and hope for miracles that it clears up overnight!
EC: Undiluted ACV is much too strong for a 5 week old kitten!
