Aww, what a sweet little friend! It is so hot here again today in Georgia, I can't even imagine not having AC! Makes my feet itch, just thinking about it. ;) Apple cider vinegar is great for so many things. Nice to here it is good for doggy frito feet! My mom usually calls it popcorn feet, so pretty close, haha. I hope the yeast dies off so he can get some good relief soon. Bless you for being such a good mama!
