Ma Yansong, founder of MAD Architects a rug that looks like a big piece of meat, which he describes as "ultimate reward for the loyal labrador." Really, though, the ultimate reward for a loyal labrador would be an actual piece of meat, right? Assuming that your dog can figure out what this rug is supposed to look like, he'll probably be incredibly disappointed to find out he can't eat it.
And honestly, that's fine. Dogs can be jerks, and we don't have nearly enough ways to passive-aggressively goad them. Now we have this rug.
