Who was willing to do what she was unwilling to do?
The vet said pay ($X) and have a 20% chance of recovery, or pay ($0), and the dog will be put down.
She was unwilling to pay ($X). The dog survived.
So who paid ($X)? Nobody.
The vet gave her dog to “Second Chances”. The dog lived, despite not paying ($X), and the vet then gave her dog away.
Note that the woman was charged for cremation fees.
The vet is scum. The dog obviously did not need ($X) to have a chance to survive, since it survived with ($0) paid. Also, the family was charged for the euthenasia and cremation of their pet.
What did it cost the vet? A bed for the night, $2 for food and water, a phone call to “Second Chances”, and printer ink and paper to print up a phony bill for services not rendered to a family in grief over having to put their family pet down.
According to the news article, the rescuers ("Second Chance") paid around $1800 to nurse the dog back to health. Surely some of that was paid to the vet, and likely most of it.
