I was just cleaning Taffy's feet and noticed that all 4 of her frogs are unattached at the ends, like they're peeled. (I got this photo off Google and put the yellow in to show where it's unattached.) Should they be that way? If not, what should we do about it? She's not lame, she doesn't walk like her feet hurt, and she stood like an angel while I was cleaning them. My mom had a horse when she was younger but doesn't remember much about the frog.... and this is our first time with a horse.
