Can a cut esophagus allow water in thoracic cavity?

[gataheart]

My malamute, Zeuse, swallowed a 1"x3" pork bone and it stuck in his throat.  The vet shoved it further down.  The next day Zeuse was panting and gaping his mouth open and shut to catch his breath.  On taking him to an
Emergency Clinic the possibility that a perforation possibly caused by this 'jamming' could be causing a buildup of water [now extremely thirsty with no seeming quench] and blood [being termed "chylous fluid"] and therefore the source of this fluid building up in his thoracic cavity was dismissed.  To my knowledge no effort has been made to determine whether in fact a perforation exists; however, Zeuse has now lost his middle lung lobe and upon a second surgery, his lymphatic system tied off.  They are now stating there is no hope and recommending euthanasia.  He has excellent appetite and between thoracocentesis is of good spirits.

Swallowing pork bones or any bones for that matter is a real danger for dogs. It can get lodged in the esophagus (which leads to the stomach), if it enters the trachea/airway then choking will ensue. If they swallow it then often an obstruction occurs and if it makes its way through then severe bloody diarrhea is usually the consequences. In this case what you are describing however does not make sense. If the bone was in fact in the esophagus, a tear or puncture will not cause fluid into the thoracic or chest cavity. The two are not really connected. Perhaps the vet said it was in the trachea and you mixed up the two terms? Chylous fluid also is not normally a side effects of a laceration, it normally is produced due to a cancerous condition.
Euthanasia is a tough decision and it is great that he is feeling okay when they tap his chest however they cant keep doing that.
