<human>: Background:
My girlfriend and I recently moved into a 2bed, 2bath, 2 story apartment. I've wanted a pug dog for an extremely long time. The first bad sign is that I purchased a one year old male pug before we even had time to settle in. Browsing /r/pugs daily caused me to be over ecstatic for my first dog.

It's been two weeks and he's grown more aggressive. My girlfriend and I both work fulltime so he is by himself for 8+ hours a day. The bottom floor kitchen and bathroom are connected so we gate him up in there with his bed, toys, puppy pads, food. He would cry for long periods of time. I purchased a Thundershirt and it's helped with his separation anxiety. 

The problem is is his growing aggression when we finally come home. He runs around chewing up misc items, licking, playful biting, etc. I left him alone for one hour last night to shower and found my glasses chewed up, poop on the carpet, etc. When my girlfriend came home to find the destruction, I have never seen her that angry. She informed me she hates the dog, wants me to get rid of him, and the decision for either him or her.

I love my girlfriend and I love my dog. I believe that although a dog is a lot of hardwork, the payoff and reward is great. By teaming up with training a dog it helps us if potential parenthood happens down the road. I'm not sure what to do - obedience school, patience, stricter training etc;
