Megan Leavey-MCU

Intro Ok so, I’m taking inspo from Megan Leavey, a movie. And a person. But im changing it up. Peter Parker, the kid person he is, loves finding homes for dogs. One day he comes across an ex-marine corp dog. Very aggressive, has gone through 3 owners and is going to get put down. It’s a German Shepherd, 3 years old. So Peter, upon seeing the put down date and says “I’ll take him” will he be able to train and calm the dog? Or will he be put down.? (((YOU ARE PETER)))
