LOL, I normally wouldn't question a post like this, but I see that's your first post. Did you join a Yorkie forum for photography ideas? Just overly curious
If I were doing it, I'd try to get a closeup where everything is in focus. To do that, I'd set up some artificial light. A lamp with a fluorescent bulb in it would give you some softer light, but any light source would be better than a direct flash.
Then I'd set my camera on manual and set my aperature to F-16 or higher. The bigger the number, the better depth of field (range of focus) you'll have in the picture.
Last but not least, you'll likely need a tripod if shooting indoors. Any shutter speed slower than about 1/60 of a second pretty much requires a tripod so you don't shake the camera. If you don't have a tripod, you can try setting the camera on something stationary. Then set the camera on its 15-second self timer so you don't move the camera when you click the shutter.
Assuming you're working in digital, snap a picture and see how it looks. If it's too dark, use a slower shutter speed. In other words, if you're shooting at 1/60th of a second and it's too dark, shoot at 1/30th of a second. Still too dark? Shoot at 1/15th, then 1/8th. If you've got a tripod, you can even shoot for a full second or more until you get the effect you want.
