The class was meeting in the classroom again, where another glowing portal was waiting to whisk them away to another place and dimension, but first? A little preamble.

"Hey, guys," Summer greeted them with a grin, "welcome back. So last week was great because I really got an idea of where you all are in portal travel, which seems like we've got a pretty open-ended book right now, which is great, there's a lot of different places we can go with this, lit-er-ral-lee, and I thought, maybe, what we could do for this class was take it just a small step further, into one of those dimensions that are pretty much exactly like the one we have here, except that they, like, call Starbucks something different or no one has ever heard of Taylor Swift before--I know, right? But the subtle ones are just that...subtle. They throw you off enough to kind of mess you up a little and make you feel weird, but that's about it, it's fairly easy to get used to. So we need to go a little bigger, and that's maybe one of the dimensions where there's a really big flip of the script, where one thing is noticably different than this dimension, and that's why I've decided this week, we're going to the Dog Dimension.

"Quick briefing: the Dog Dimension is basically a dimension where dogs evolved like humans, and humans involved like dogs, so dogs are the dominant species and humans are basically pets. Which can be a little off-putting, but also, it's kind of important? As, like, a reminder that humans aren't shit everywhere, you know? We could probably stand to be taken down a few notches in some dimensions, there's even dimensions where people are, like, furniture and phones, and I almost considered going there but I thought you guys would appreciate not having sentient armchairs trying to sit on you."

Yes, that was an actual sentence that came out of her mouth.

"The biggest threat we might face in the Dog Dimension, other than the giant birds," yes, that was randomly thing in Dog Dimension, don't ask, "is someone trying to adopt you, probably, or take you home, so keep that in mind. Luckily, the current emperor of the Dog Dimension is actually our old family pet, Snuffles, so I've got an in. Things got a little rough between us when my grampa gave him sentience in our dimension and then he tried to take over the Earth, but, you know, that's when we sent him off to Dog Dimension, and honestly? It is working so much better for him now. So, let's everyone get ready, hop on through the portal, we'll meet some dogs and you can ask questions and experience a world where dogs are humans and humans are dogs!"
