Plain-English summary
A group of 21 dogs with carotid body tumors (a type of rare neck tumor) underwent surgery to remove them. Unfortunately, more than half of the dogs experienced complications after the surgery, including breathing issues and aspiration pneumonia. Despite these challenges, the overall survival rates were promising, with many dogs living over a year after the procedure. The study suggests that while surgery can be risky, it can also lead to a good chance of long-term survival for dogs with these tumors.

Abstract
Carotid body paragangliomas represent an uncommon neoplasm in dogs. The objective of this study was to report outcomes and complications associated with surgical excision of carotid body paragangliomas in 21 dogs. Cases were recruited retrospectively via medical record review from 9 veterinary speciality centres. The perioperative complication rate was 52% (11/21). Complications encountered in this cohort related to removal of carotid body tumour included airway obstruction, aspiration pneumonia, megaesophagus, unilateral laryngeal paralysis, coughing and Horner's syndrome. The overall perioperative mortality rate was 4.7% (1/21 dogs) and median survival time was 554 days for the six patients with known dates of death. One- and two-year survival rates were 61% and 42%, respectively. This is the largest collection of carotid body paraganglioma cases reported in veterinary literature. Based on these results, surgical resection of carotid body paragangliomas was associated with low perioperative mortality and long survival times.
