Its Azi from chap 46, the dog that peed herself in fear of her owner& didn't sell well and thats why the owner abused it.
At the end our mc vet was talking with that director guy and he said usually abused animals dont do well in shelters& and our mc said he'd take Azi, the dog in.
Right after this chap our mc isnt able to save a dog and builds accepts the offer for a big hospital but we never hear from Azi again.

Yk the dog that was abused by the owner, it was a spaniel that came in and the vet said he would take him in while it recovered.
Did that plot get lost? ╥﹏╥
