His New Collar

Every picture tells a story, and this one is a tale of overconfidence -or maybe just cluelessness. That's the cat door around his neck. This puppy thought he was small enough to go through, just like the cat he lives with. It doesn't work that way. His head went through, but getting it back out was a different story. The uploader doesn't say whether the dog broke the door off or the human had to disconnect it, but the result is a sorry dog with a self-made collar of shame who may our may not have learned his lesson. -via reddit
