This little boy, Jeremy, is lucky to have such a good feline friend. The family tabby, Tara, body-slammed and chased a dog that had snuck up behind Jeremy and grabbed him. Jeremy came out of it with only a few stitches. There is a gif and video of the encounter which I'll post below - it's kind of scary, in that it involves seeing a dog grab a four-year-old boy and drag him (and the video has images of the wound he received), but it all ends well when Tara body-slams the dog into next week.
Video can be found here at the Laughing Squid.
