I like the solution the shelter came up with. Everyone is happy all around, especially Otto.
Our rescue had a similar dilemma in 2011.
A German shepherd was turned in to the shelter for euthanasia by a family with financial constraints. The vet determined his life could be saved so we decided to save the dog, pay for the surgery, then return the dog to the family.
Here’s the reunion.
