Plain-English summary
A group of 7 young male Pugs, aged between 4.5 months and 4 years, were diagnosed with lung lobe torsion (LLT), a serious condition where a lung lobe twists and cuts off blood supply. These Pugs showed no prior health issues and were significantly more likely to develop LLT compared to other breeds. After surgical treatment, 6 of the 7 Pugs recovered and were discharged from the hospital without complications or recurrences. This suggests that while Pugs may be more prone to this condition, their chances of recovery are quite good.

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.
