VIRAL VIDEO: Dogs in wheelcarts play fetch

GERMANY -- Here's a video that will surely make you smile -- disabled dogs in wheelcarts playing fetch.

Gritta Goetz, who operates an animal sanctuary in Germany, posted the video on YouTube.

One of her own dogs, named Rina, was paralyzed after her former owners used her for target practice. Now, Rina and the other disabled pups are learning to play again.

The video shows dogs both with and without wheelcarts racing up and down a path in a field.

The disabled pups don't seem to care that they're strapped to a contraption. They're just excited to be out and about, free to roll around to their hearts content!
