It's a tumor and we are waiting on lab results to see if it's cancer. His incision is huge and he wants so badly to lick on it but he's too big and can't bend like that! We really hope that we get one more summer of camping with him, he loves being away with us. Eric and the hunting boys hate to lose their guard dog. We've also found out that his thyroid is bad and he is now on meds. I am thankful that he is acting like the same ol Nic.
