Ken-Dogger: "Okay today class we will be discussing the concept called over-exertion. This happens when those who don't know their limits, exceed their limits. This is an example of over-exertion in the canine world."
Student: "I've seen my doggie just like that, my daddy says it's called 'played out'."
Ken-Dogger: "Yes, yes, you can call it played out..."

We call it goobed out*. Because the beagle acts like a goober and runs around in circles attacking socks, until she runs out of goob.
*Only applies to goobers.
