Ouch, poor Dungy, that does look painful...Tia tore one like that as well and as I don't clip nails I took her in to the vet as it was soo far down and let them clip it...Yes, she was a bit sore for a few days, but nothing major.....Give that sweetheart a nice hug for me and try a sock on it, maybe that will protect it a bit til you can take him in....
