Adopter had a young and healthy dog from a rescue euthanized.
The rescue's contract stated that dog should be returned if the adopter was having any considerations to rehome or euthanize. Their vet euthanized the dog due to behavior; with no bite history, no animal control report, no reports from 3rd party on aggression - and the dog had been reduced to "foster" status by the rescue, who stated they would get the dog as soon as the the rescue owner had recovered from surgery. The dog was chopped (to the rescue) and was never checked.
