I feel that. We had a dog back in the day that could have been fixed and lived a happy life, but the farm vet put them down without permission. I know, totally against every rule and legality ij the book. This was just when the vet had switched from being a farm vet to a domestic vet, and still held the same mindset
They got sued to the max later on. We didn't sue because we didn't realize at the time. We thought when she called to say he was done, she had a sincere reason. It was several more attentive people who did a lawsuit after the same thing happened to them.
The dog could have lived a fine life without a leg, which we were willing to provide, but she didn't think of asking us. She just said he was done and that was it. Rate us autistic for believing a vet. We didn't know.
Shes still the same but now ONLY vet in town so we have actually taken our pets hours away to the nearest town to get checked out. While she has learned a lot from being the only vet, and thus responsible for domestic pets, we don't take our pets to her for anything but check ups.
