healing

Hi my 8 week old doberman male got his ears cropped 8 days ago and today he pulled out a stitch while i wasn't home and i'm very worried even though it doesn't look like he pulled skin his ear has a lot of scabs but i'm assuming its normal but i'm nervous about the stitch he's my first dobie so...

Ruger is young, but right now it seems that a short 12-inch lead and the classic "choke chain" are making him heal quite nicely. What about your Doby and how did you successfully train him to heal when walked?
