Itchy Ears

I have been cleaning my dogs ears out with apple cider vinegar lately and I think this has really helped her out. She has been really itching her ears lately and they were kinda stinky actually. So I put some vinegar on a cotton ball and just washed them on the inside of the ears and I have noticed a decrease in her itching her ears and they do not nearl stink as bad. Although they smell like vinegar when I put it on but that is better than what it was smelling like!!
