What's wrong with this picture?

Here's Tristan at five months with his hedgehog buddy. Tristan loved his hedgehog - it squeaked, rattled and grunted. So what's wrong with this picture? Well, there are three intact items: Tristan, the hedgehog and the Italian leather loveseat. Guess which is the only remaining intact thing? Tristan soon reduced the loveseat to its bare frame. I gave up replacing the hedgehog after he went through two of them.

Looking at the picture now I find it hard to believe that Tristan was this big at five months and amazing that dogs can grow so big so fast.
