My wife has a Yorkshire Terrier, he is a pretty cool little dog. Usually when you see pictures of Yorkies they look like really gay dogs, but my wife keeps her's hair short and he looks pretty cool. My wife's dog rarely ever barks, except when he needs to go out. Sometimes when he thinks he sees something he lets out this weird little growl that sounds just like an Ewok. He walks around the house and plays with his little toys and doesn't get too annoying.

I highly dislike dogs, just not a pet guy, so I really didn't like the idea of having a dog in the house, but I had to make a compromise for my wife. He grew on me pretty fast, and all the things I hate about house dogs he seems to be lacking, doesn't bark, doesn't beg, does't jump up on people.

As far as things you need to know, if you get a really small dog like a dachshund, watch your step. My biggest fear is having to tell my wife I stepped on her dog and killed it. Also, if you get one young enough that it is not already house broken, make sure you house break it. Unless he has a doggy door or someother way out of your house/apartment on his own, you've got to take it out at least a couple of times a day. Smallers dogs are nice because they eat less and save you money on dog food.
