“…Although respiratory CS have been reported in dogs with sHH, they were in brachycephalic breeds and consistent with BOAS 30 . The high incidence of respiratory CS in 58% of dogs in our study is consistent with a recent report finding that dogs presenting with respiratory CS frequently have occult alimentary disease 2 . In our study, 25% of dogs were presented with exclusively respiratory CS.…”

“…Videofluoroscopic swallow studies represent the criterion standard for evaluation of dysphagia in dogs. 2,23 In our study, VFSS was superior to radiographs for detecting sHH. Furthermore, this modality allowed characterization of concurrent AeroD such as GERD.…”

“…Relevant radiographic metrics inclusive of caudal esophageal fluid (present or absent and radiographic view where observed), aerophagia (present or absent), findings consistent with aspiration pneumonia (AP; cranioventral distribution of an alveolar or interstitial pattern), and hypoplastic trachea were obtained from finalized radiographic reports where available. After enrollment, all VFSS were re‐evaluated by a single investigator with experience in interpretation of VFSS by the below‐mentioned metrics (MG) 2,23,25 …”

“…Reflux limited to the distal third of the esophagus was considered physiologic. Aerophagia was defined as gas comprising > one‐third of the bolus volume or after filling, > one‐third of the gastric volume 2 . Esophageal hypomotility was defined as incomplete or ineffective peristalsis 2 .…”

“…6,[9][10][11] Sliding hiatal hernias (sHH; hiatal hernia type 1) are known contributors to GI CS in dogs that have been linked to GERD, EERD, and respiratory pathology, making them an example of an AeroD. 2 Sliding hiatal hernias frequently are identified in brachycephalic dogs, with breed predispositions in French bulldogs 12 and Chinese Shar Peis. 13 However, sHH is not exclusive to this population.…”

Background Aerodigestive diseases (AeroD), hybrid disorders between the respiratory and gastrointestinal (GI) tracts, may present without GI signs. Sliding hiatal hernia (sHH) is an important AeroD in brachycephalic dogs linked to respiratory pathology. The spectrum of other AeroD and respiratory clinical signs (CS) in brachycephalic and nonbrachycephalic dogs with sHH is unknown. Objectives Characterize CS of AeroD in dogs with sHH, compare CS between brachycephalic and nonbrachycephalic dogs, and compare thoracic radiographs and videofluoroscopic swallow study (VFSS) for diagnosing sHH. Animals Sixty‐seven client‐owned dogs with sHH. Methods Medical records of dogs with sHH presented to the veterinary teaching hospitals at Auburn University and the University of Missouri between 1 January 2009 and 31 December 2020 were retrospectively reviewed. Between group, comparisons were made using Mann‐Whitney test, Chi‐square analysis, and Spearman correlation ( P < .05). Results Dogs with sHH presented with exclusively GI signs (28/67), mixed respiratory and GI signs (22/67), or with exclusively respiratory signs (17/67). Wheras brachycephalic dogs were not significantly more likely to present with respiratory CS ( P = .145), they were younger ( P < .001), and more likely to present in respiratory distress ( P = .02), and with radiographic evidence of aspiration pneumonia ( P < .001) compared to nonbrachycephalic dogs. Six of 12 dogs with normal thoracic radiographs having sHH presented with respiratory CS. For detection of sHH, VFSS was superior to radiographs ( P < .001). Conclusions and Clinical Importance Dogs with sHH may present with exclusively respiratory signs. Respiratory signs may be more severe in brachycephalic compared to nonbrachycephalic dogs. Videofluoroscopic swallow study was superior to thoracic radiographs for detection of sHH in dogs.
