Oh my gosh. That is absolutely horrible, I'm not going to lie. I seriously think I remember seeing something like this on Animal Cops or something, from when I used to watch TV. I'm the same age as you, if I remember you saying 14 correctly, and my Labrador Retriever has Seperation Anxiety (sounds like yours does too... meaning - well, read below), and if my dad simply /mentioned/ a shock collar I would scream at him and say that we would NOT keep her.
Plus, if your dog has Seperation Anxiety (a problem I have had experience with for the past 3 years of my life, so I know my fair share about it), TAPING ITS MOUTH SHUT will make it worse. And leaving it out in the cold will make it worse, too.
I just hope you have your dog's best interests in mind and relize that your dog is in a horrible situation, and needs to be re-homed. I'm sorry if this seems harsh, but it's the truth. Your dog shouldn't have to go through that.
