Retired vet. Whenever someone brought in a perfectly healthy animal to be put to sleep, I always encouraged it to be done privately in their absence. If they agreed, I secretly sent the animal to some friends who run a rehoming centre. Still charged for the "euthanasia".
@fesshole I took a German Shepard (my favorite breed of dog) to my vet for euthanasia.
If the kids (4 @ 4-8 years of age) went running the Shephard followed its instinct and "took them down."
The vet tried to talk me out of it. I said "it's just a matter of time before this turns bad."
3 months later I saw that dog with another human pushing a stroller. I was furious! I told the owner the story. HE put the dog down himself.
F*ck any vet who does this!
