Abstract

This report aimed to study symptoms and causes of brachycephalic obstructive airway syndrome (BOAS) in brachycephalic dogs and to determine appropriate surgical procedures for these symptoms by reviewing literatures and examining four case studies conducted at Veterinary Specialist Service Hospital, Underwood, Queensland, Australia. The cases included a 6-year 3-month old Staffordshire Bull Terrier (case 1), a 1-year 5-month old French Bulldog (case 2), an 8-month old French Bulldog (case 3), and an 8-year 8-month Pug (case 4). Those dogs went to the Veterinary Specialist Service in a worsen state of respiratory problems, including the upper respiratory noise (case 1, 2, 3), decrease in exercise tolerance, respiratory struggling (case 1, 3), regurgitation (case 1), coughing, sleeping difficulty, respiratory stridor (case 2), nasal discharge, dyspnea, bloating, and tachypnea (case 4). Examinations revealed the causes including the elongated soft palate (case 1, 2, 3, 4), stenotic nostrils (case 2, 3, 4), tonsils inflammation (case 3) and everted laryngeal saccules (case 4). After surgery, the dogs were recovered in intensive care unit within 2 days, and then discharged. Scheduled re-examination one week later showed improvement in the respiratory health in all cases. Overall, major complications occur in 10\% of cases; however, this surgery is vital and can be totally applied in Vietnam where brachycephalic dogs have become a popular companion.
