Is AUTHOR wrong in the post ? POST : I'll keep the story short.

Me and my girlfriend have been together for over a year now and I'm fairly close with her family. Their family just got a puppy in September and he's been doing well and they love him. Yesterday they adopted another puppy (same breed) and today they're returning him because it turns out he is not crate/potty trained as advertised and he's not getting along well with the other dog. 

I know this probably makes sense for her family but I just feel so bad for the puppy and it's made me upset; I guess the puppy has already been returned once before. AITA for having these feelings? I know it's not my family or anything but it just makes me upset.. I feel like maybe they rushed into getting another dog without thinking about how feasible it would be and now the puppy is getting returned.
