Unfortunately, due to the coronavirus, a lot of shelters have been pushing hard to get as many animals adopted out (or at least into foster homes) as they can, so they can keep the shelters as minimally staffed as possible, and, in the case of public open-admission shelters, not have to euthanize otherwise adoptable animals.
Dogs really don't do well in shelter environments; even the best ones are enormously stressful. So Corissa and J were more than likely able to adopt this small, high-energy (and likely stubborn as fuck, as Jack Russell and Rat Terriers tend to be) dog because the shelter was trying to get animals out of the shelter before it had to close to the public. In normal times, they might not have been approved, but when times get desperate a lot of shelters will (unofficially) relax their adoptions criteria.
And of course Corissa's got to adopt a new dog when the threat of quarantine is looming, because she might get bored, and a cute new dog will get her plenty of attention on Instagram. I'm sure it's also a distraction from the fact that if she gets a bad case of Covid-19, she's pretty much guaranteed to die.
Eventually, she'll get tired of this dog and its demands (without ever having done anything to train it and give it adequate exercise and enrichment so it's easier to live with), and it will go away. But for now, she needs a distraction and something to post about on Insta besides how fucking miserable she actually is, and a new dog suits that purpose.
There are plenty of small brands making plus-size underwear that she could approach--but no, she's got to pester Aerie. And I'm pretty sure it's because those small brands don't have national name recognition, and thus lack status. Corissa's basically back in middle school, resentful of the fact that she can't wear the same trademarked brand names on her clothes as the thinner, prettier girls do, because to her wearing those brands proves she's cool.
