<human>: I want to say first and foremost, that I don't want to be, just not sure how to care for a small dog.

Alright, so first off, it's my aunt's dog, and I'm looking after it for a few days. It's a chihuahua, and I think I remember her saying it had a problem with abuse in the past, not 100% on it, though. She's living with us, and had to leave for the weekend, and I'm the only one here, so I'm looking after it.

It mostly said under my aunt's bed, which I was fine with until I had to take it out to use the bathroom. It wouldn't come out, so I reached in for it. It snapped and growled, and I backed off for a while, threw some food to it, and let it cool off. I came back, and tried the same thing. Same reaction, but this time it bit me which pissed me off. I'm not exactly proud of my handling of the situation from there, but suffice it to say that I came out on top of it, and neither of us felt friendly towards the other. This was all took place last night.

This morning, I locked it out of her room, so it's sat in the hallway of her room, not eating or anything. When I approach it with a leash, it growl and snaps at me. I don't want to be an asshole to this dog, but it's leaving me little choice. Any tips on handling this situation?

Can you provide a brief rundown of the text in within 3 sentences?
