Another Excuse Not to Vacuum

Freckles is our new dog and he is definitely changing life at the Robinson house. Not only does he hate the vacuum, he also loves to eat non-food items.
Like socks.
And plastic water bottles.
And pine cones.

When we try to take those things away from him, he runs.
And he's fast.
Really, really fast.

If he finally gets caught, he tries to keep the item from us permanently.
By swallowing it.
I'm still waiting for the DS screen cloth to make it way through his digestive system.

How many days should I wait before I start to worry?
