First off my 2 boys are 11 weeks old and are half collie, half lab they will come and sit when we are in their pen, but when they are out they listen about 50% of the time if someone else is out side they listen 0%. What is the deal with these little guys are they just to young to deal with destractions and obedience? Please help.

Also one of them will bite and growl when touched if he is chewing on his bone. The other one will not. The one that does will bite out of anger because he thinks I am taking his bone, also he does not do this food only his bone. He has done this 2 days in a row and broke skin this afternoon please help.
