I'll start by saying in general I don't know that an ESA for a college student is a good idea, and an untrained husky puppy in a small apartment is not the right fit. However I've learned to never say never and none of us know the girl well enough to pass judgement as to what she may need for her mental health.
It seems to me the latest bit of news is an indirect consequence of the "roommate agreement." The other roommates don't want the dog and made it clear they would refuse to help in any way. Instead of the expected consequence (that she give up the idea of having a dog), it backfired and she has found other friends who are willing to help her. It actually leads more credence to her claim of needing some form of "support" since she is willing to go to all this effort and others are willing to help her. I still don't think she handled the situation well and the animal she picked is not correct for her living situation. But I do think this girl must be struggling with some issues and she either didn't share her challenges with her roommates early in the semester, or the roommates may have turned a blind eye. Her other friends are willing to step up and help, which also makes me wonder how close the roommates were to begin with. When I was in college, by the time you were getting an off-campus apartment it was usually with friends or those you knew quite well even if you didn't hang out together all the time.
It sounds like there has definitely been a lack of communication between all the roommates. It's a good lesson for all involved to consider the impact their own actions and decisions may have on others - especially others with whom they share living arrangements.
