According to the National Retail Federation, Americans will spend $480 million on costumes for their pets this Halloween. That's almost half a BILLION dollars.
And it's more than double what we spent on pet costumes back in 2010.
And their theory on what's pumping up the spending is Instagram. Everyone wants to share a picture of their dog dressed as Captain America. Everyone.
The most popular pet costumes this year are: Pumpkin, hot dog and bumblebee.
