I would not tell a kid, I put the dog down. Understanding death is not easy at a young age. Kids dont understand money and why its either not affordable or practical, or medically possible. I took it out on the vet, who was a fishing partner of my father.

Not my business what you said, just wanted to add a perspective of a kid, that didnt like it one bit. Someday, he might see that done to a person. I hope he has the age and the support to deal with it. It can screw you up.

Sorry for your loss.
