**Footnote of the events that led to the decision to let Lucas go:
Lucas's having laryngeal paralysis was confirmed during the first surgery to remove his teeth, and it became the chief concern during the two subsequent surgeries he would have. Many dog owners know about this, but for those who don't, in the normal respiratory cycle when inhalation occurs a laryngeal muscle contracts and opens the airway. Laryngeal paralysis does not allow this to happen and dogs like Lucas have to inhale against an obstructed airway. That airway became totally obstructed making it very, very difficult and nearly impossible for Lucas to breathe on his own. Treatment after more than 12 hours should have helped, but sadly it was ineffective. The decision to let Lucas go was made with the help of a kind, caring and compassionate vet who I met last year when she and her family adopted from the rescue.
