However, later Haruhi says this about this about the dogs:“This morning, I noticed that she didn’t bring one of her dogs out for a walk. When I asked her, she told me that he had died of illness last night. She didn’t go into the details, but from what I heard, it seems that he was sent to a vet."
And of course for the rest of the chapter Higuchi's dog is alive.“Even the vets are baffled. Physically, he’s perfectly fine, but it seems that he’s too unmotivated to do anything. The same goes with Higuchi-san’s Michael! They won’t even budge to eat!”
So, is this a translation error? Or did Nagaru-san feel bad about killing off a dog and changed his mind midway through?
