Obama dog may be gung-hoe for the new garden

Though it's already been announced that Sasha and Malia will be picking up after the new first dog, first lady Michelle Obama has demonstrated she's not afraid to get her hands dirty. Last week, with the help of her daughters and local fifth graders, she broke ground for a new White House garden.

While not every dog is a digger, the rule seems to be, the more elaborate the garden, the more interested the dog is. So, two things the Obamas should keep in mind:

1. Set boundaries right away. It's not difficult to train a dog to stay out of the garden, provided he hasn't already made it his favorite play area.
 2. Some fertilizers and lawn treatments are harmful to dogs. Read before you seed!
