Plain-English summary
A group of dogs with laryngeal paralysis (LP) were examined for signs of gastroesophageal reflux (GER), which can cause symptoms like coughing or regurgitation. The study found that these dogs had more acidic reflux events compared to healthy dogs, indicating that LP may lead to increased stomach acid reaching the esophagus. While the overall number of reflux events was similar between the two groups, the LP dogs had a higher frequency of acidic reflux. This suggests that if your dog has LP and shows signs of reflux, it may be worth discussing treatment options with your veterinarian.

Abstract
OBJECTIVE: To determine the frequency, nature, and magnitude of gastroesophageal reflux (GER) in dogs with laryngeal paralysis (LP). STUDY DESIGN: Prospective comparative clinical study. ANIMALS: Client-owned dogs with LP and healthy client-owned dogs (n = 6 each). METHODS: Dogs underwent sedated laryngeal examination for diagnosis and grading of bilateral LP and for placement of a nasoesophageal dual pH/impedance probe. Endoscopy was used to confirm probe location and evaluate the distal esophagus. Data were recorded continuously. GER was defined as pH<4 or >7.5 lasting >2 seconds reaching a magnitude of 2 impedance sensors proximally. RESULTS: The median total number of GER events per hour was 0.64 (range, 0.44-1.6) for the LP group and 0.53 (range, 0.38-1.0) for the control group (P = 0.259; power = 0.50). The median total number of alkaline regurgitation events per hour was 0.37 (range, 0.17-0.93) for the LP group and 0.46 (range, 0.25-1.0) for control group (P = 0.575; power = 0.57). The median total number of acidic regurgitation events per hour was 0.22 (range, 0-0.70) and 0.0 (range, 0-0.14) for the LP and control groups, respectively (P = 0.025). Acidic reflux events reached the proximal pH sensor in 2 dogs in the LP group for a total of 4 reflux events and in 1 dog in the control group for a total of 3 reflux events (P = 0.673). CONCLUSION: Based on the limited number of dogs studied, it appears that dogs with naturally occurring LP have increased acidic reflux events compared to clinically normal dogs. GER can reach the most proximal part of the esophagus.
