It’s common for dogs and cats to understand at least a few key words, like “eat” and “out” and “NO!” However, they can also become accustomed to certain sounds, which can trigger a behavior in them that you wouldn’t expect. Take this dog who was conditioned to go crazy whenever it heard the Windows 7’s logout na-nuh noise.
Whenever the owner logged out of their laptop, it was a sign that the owner would get ready to go out. For the dog, going out meant chilling at mom’s house. Now, years after the user has switched to Windows 10, the dog still can’t help but jump and dance whenever the na-nuh sound plays on YouTube.
