Maddox did something and his big toenail basically fell off. It’s just hanging on but he refuses to let me have a good look and he won’t even let me touch it.

I managed to get a bandage covering it and put a sock on him so it doesn’t catch on anything.

Is there anything the dr can do? Or is it likely she’ll just tell me to do what I’ve already done? I am going tomorrow with Maisy anyway. Should I have him tag along so she can look?
