Barbie and the Pooping Dog

Ummm?????

This is what some people are saying about this toy:

I bought it only because I couldn't believe someone could think up a toy like that.... The dog that eats its own feces... over and over again.... This toy should be called Barbie in The Dante's Hell of The Scatological Dog....

The dog eats "dog biscuits", then expels them through a hole below the tail. Then the dog "eats" the expelled dog biscuits again. What is this supposed to teach? That dogs eat their own excrement? This is gross.
