DISCLAIMER: It has been brought to my attention that since this design has the push \ pull mechanism that it is not truly 100% dog proof as smaller breed dogs can stick their paw in and push the trigger down and get caught. If you want a truly dog proof trap I suggest going with one that only has the pull mechanism. There are several out there to choose from.
