Or, having a realistic idea in advance of catastrophe about what you are willing to pay in an emergency. I lost a wonderful mare a year ago to a horrific torsion colic. She was not a surgical candidate for a variety of reasons that presented themselves that night, but even if she had a better prognosis, the cost would have exceeded what I would be willing to pay. I miss her every day, but wouldn’t have made a different financial decision.
I think people need to have an honest conversation with themselves (and any partner with shared finances) about what you are willing to do well before you are facing a difficult emergency moment. I love my animals, but I have a clear line in my head when it comes to finances. Not jeopardizing my family’s future for an excessive vet bill.
