You definitely are the wrong guy, or probably it's more likely that you are a girl, to keep a dog. You sound like you would get bored pretty fast of it and you surely did not consider the work you will have with it. Not to speak of yearly fees, doctor, food and so on.

And if you really get such a dog for cheap then it might come from one of those dog breed farms. Brought out from incest, having multiple illnesses that show up some time later.

If you really would love that dog then you could feel like shit.

Besides that... you want it because others look down on you? How superficial are you?
