Nugget, one of my 14 week old girls, has a little flap of skin on her left foot and a black dot inside of it (pictures below). It doesn't look swollen, although I may have convinced myself it's slightly bigger than the other, and no redness or limping. I soaked it/cleaned it and sprayed with Vetericyn. Figured I'll do this 2 times a day and monitor. I'd welcome any thoughts and advice. Thank you.
