I bought one of those plastic things from Target that has maybe 3 drawers and then I bought a smaller one with three drawers that is the size of a jewelry box. I keep it upstairs in the spare bedroom.
In the big one I put:
Drawer #1 - collars, harnesses, leashes, ID tags, poop bags
Drawer #2 - all her clothing
Drawer #3 - shampoos, conditioners, Heartguard, Frontline, brushes, combs, beauty supplies, etc.
In the little one:
Drawers #1 and #2 - bows and barretts (why I bother I don't know, since she won't leave them in!!!)
Drawer #3 - jewelry and bling tags
I have a puppy toy box in the LR with all her toys and she goes in there and helps herself - I clean up at the end of the day.
I have a treat box in the kitchen with her treats.
Hope that helps a little.
