Who needs a dog?

I'm not an animal person. (it was in the prenup that there would be no pets in our marriage) But my brother is always trying to tell me that a dog is great for eating all the food that inevitably falls on the floor when kids are eating.

But Zoey has taken to sitting under the table and picking up all the food that has fallen and eating it herself.

So I ask you, who needs a dog when you've got a Zoey?
