I'm deeply sorry for your loss. I live with CT every day in my older dog and it is scary and difficult to manage. I dont think you should beat yourself up here. You did the best you could under the circumstances you were dealt. The sedation for xrays isn't damaging but the intubation (when they come off) can be hard on a dog with CT. I have posted about my experiences with the various drugs and how many do not work for him on his profound collapse in the same location as your boy. Hycodan in a very high dose is keeping him alive and in a good state most days. But if he ever struggled to breathe as your dog did, I would have done as you did and let him go. Sometimes this condition cannot be helped. The trachea is collapsed and they breathe through a straw. I'm again very sorry for your loss and please don't second guess your actions, you did all you could do under the terrible circumstances.
