Newsround's April Fools story

It's April Fools' Day - traditionally a chance to play practical jokes on your friends.

Not one to be left out, Newsround had its own April Fools' Day joke - a dog collar with hidden cameras so you can record your pooch while you're out of the house, then analyse his activities through a computer.

If only that were true....It featured on our Newsround bulletins this morning. Did you spot it was a hoax?
