Jack Russell Biting Me

by Crystal
(Canada)

Hi
I have a 3yr old jack and he usually is very good and listens but lately he has been very territorial when it comes to us eating dinner or a snack.

He will not listen for anything and I have tried to pick him up and put him in the other room and he has bitten me a couple of times.

How do I punish him with out hurting him, and for him to know that this is wrong??

Please help- people tell me to get rid of him. But I want to desperately fix this issue. Please help. Thank you
