this last season my shock collar has not been working, so before deer hunting I sent it in and got a new one. Do you think that dog knows when that collar doesn't work?? I havn't got a chance to take him out since begining of DEC. my dad hunted him with the new collar, but nothing changed. I can't figure this out . Although... ... he does freak out during rain, thunder, or lightning storms. I know this stresses his heart, when I put him in the shed, his eyes are BULGING out of his head and bloodshot. the dog is nuts! like coonhunter22 said, i think he doesn't have much confidence as he used to. because almost every night, the first drop we would make was good, but anything after that he blew it away! nothing. normally in a hollow or loosing them in the creek. our season in closed now so I'll have to see what happens next year.!! everyone cross your fingers!!!!!
