Every time i wash her i have tried to squeeze and scrub it of but nothinf gives. Only tiny pieces at a time. And ive tried to take tweezers but its to thick of a scab or poop idk. But itbstill needs to come off or fall off. But maybe with the alochol in the witch hazel can help dry it out and than ill continue to put coconut oil on it in between and hopefully that can help it. And for toe i cant tell if its bumble foot or not.but there are ittle dry scabs or something around the nail.
