Timid Pup (Update)

I got an update on my pup. Last sunday I finally got tired of messing with him and I pulled him out of the pen and put him on a chain close to the house where I could pet him and he could get used to people. Hadnt made any progress till this point and by Wednsday he was coming to me and jumping up on me. Last sunday I put him in a pen with his brother and my 11month old pup and he laid there while the other dogs was bayn and let 6 pigs run over and trample him. Today I put him back in there and he bayed his @ss off. He got hit 4 times in a row and got right back in their face. He was even putn teeth on em,which I dont wont one real gritty but he only 3 1/2 month old and that might be corrected in time. He did a complete turn around in less than week. Its the pup in my profile pic. Just proud of him and glad I didnt cull to quick.
