It seems like his right ear is bothering him. He shakes his head and scratches at it a lot. I checked his ear and its crystal clear so i'm not sure what the problem is. Here's a picture. ****EDIT:****** i was about to clip his nails when i noticed one of his nails was bleeding. It looks like a rotten nail, its all black. I don't know how this could of happened and i'm not sure what to do. My mom said to put peroxide on it but i would like to make sure.
