Abstract
OBJECTIVE: To determine whether there is a predis-position for lung lobe torsion (LLT) in Pugs and describe clinical findings associated with LLT in that breed, compared with findings in other breeds. DESIGN: Retrospective case series. ANIMALS: 7 Pugs and 16 dogs of other breeds. PROCEDURE: Information collected from records included signalment, history, lung lobe affected, results of clinicopathologic testing, histologic findings, diagnostic imaging results, surgical treatment, and outcome. RESULTS: 23 dogs were diagnosed with LLT, 10 of which were large-breed dogs and 13 of which were small-breed dogs. Seven of the small-breed dogs were Pugs. Pugs with LLT were significantly overrepresented, compared with the general hospital population. Affected Pugs ranged in age from 4.5 months to 4 years (median, 1.5 years). Six of the 7 Pugs had no predisposing conditions, and 6 were male. Six Pugs survived to discharge. Of the other small- and large-breed dogs, 3 of 6 and 5 of 10 survived to discharge, respectively. None of the Pugs were readmitted for complications or recurrence. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that young male Pugs may be predisposed to developing spontaneous LLT. The prognosis for survival and resolution of clinical signs in Pugs with LLT appeared to be excellent. Factors contributing to the development of LLT in Pugs are not known.
