My almost 3 week old light Sussex, has string around his/her tongue...I managed to cut the Length and cut it apart but it is embedded in the tongue! It is about half way on the tongue, and the tip looks dead. Should I let him/her rest for the night and try to remove again tomorrow? when I pulled it pulls the tongue I was worried I may pull the tongue out Is there something I can do to stop infection? Or the whole tongue dying?
