title: Aspiration pneumonia in the Irish wolfhound: a possible breed predisposition.
abstract: BACKGROUND
  Anecdotal reports suggest a recent high prevalence of aspiration pneumonia in Irish wolfhounds, prompting further investigation into the incidence of the disease in this breed.
  
  
  OBJECTIVE
  To investigate the possibility that Irish wolfhounds have an increased incidence of aspiration pneumonia, and to consider possible predisposing causes in this breed.
  
  
  METHODS
  Retrospective review of medical records from the Small Animal Specialist Hospital, Sydney, from January 2008 to December 2012 inclusive to determine the total hospital incidence and individual breed incidences of aspiration pneumonia.
  
  
  RESULTS
  The total hospital incidence of aspiration pneumonia was 0 · 5%. The Irish wolfhound had the highest breed incidence, with 9 of 25 dogs (36%) diagnosed with aspiration pneumonia. Four of the Irish wolfhounds had a predisposing cause identified; one having a choking episode, one having gastric bloat, while two were diagnosed with laryngeal paralysis after it was specifically investigated because of clinical suspicion. Five had no underlying cause of their aspiration pneumonia determined.
  
  
  CONCLUSIONS
  On the basis of the hospital population studied, the Irish wolfhound has a high incidence of aspiration pneumonia. Further investigation into the possible predisposing cause(s) in this breed is warranted.
