To evaluate the association of mesenteric volvulus (MV) in New York Police Department police working dogs (PWDs) with and without a prior prophylactic laparoscopic gastropexy (PLG).


370 PWDs (82 with and 288 without PLG).


Medical records and surgery and radiology reports were reviewed from 2012 to 2022. Signalment, pertinent history (medical and surgical), gastropexy status, temperament, and training type were recorded. Statistical analysis was used to identify the relationship between prophylactic gastropexy and MV within the patient population.


3 cases of mesenteric volvulus were noted in this patient population. Two (2.4%) of the 82 PWDs that had undergone prophylactic laparoscopic gastropexy developed MV, whereas 1 (0.3%) of the 288 PWDs that had not undergone a gastropexy procedure developed MV. Police working dogs with PLG were estimated to be at 7.2 times greater odds of MV (point estimate OR, 7.18; 95% CI, 0.642 to 80.143); however, the low incidence of MV in this population limited statistical power, and thus this effect did not achieve statistical significance. Evaluation of MV incidence in additional populations of working dogs will allow greater precision in the point estimate.


Prophylactic gastropexy may be associated with an increased risk for MV. However, patients without prophylactic gastropexy are at risk for gastric dilatation and volvulus, which is more common than MV. Therefore, the authors continue to recommend prophylactic gastropexy to decrease the risk for gastric dilatation and volvulus.

Objective—To examine postoperative ocular hypertension (POH) and other variables as predictors of the risk of developing glaucoma after cataract surgery in dogs.

Design—Retrospective study.

Animals—220 dogs that had cataract surgery.

Procedure—Medical records of 220 dogs (346 eyes) that had extracapsular cataract removal or phacoemulsification of cataracts were reviewed. With respect to glaucoma development, 8 variables were analyzed, which included development of POH, breed, sex, age at time of surgery, eye (right vs left), phacoemulsification time, intraocular lens (IOL) placement (yes or no), and stage of cataract development. Eyes developed glaucoma within 6 or 12 months of surgery or did not have signs of glaucoma at least 6 or 12 months after cataract surgery.

Results—Of 346 eyes, 58 (16.8%) developed glaucoma after surgery. At 6 months, 32 of 206 (15.5%) eyes examined had glaucoma; at 12 months, 44 of 153 (28.8%) eyes examined had glaucoma. Median follow-up time was 5.8 months (range, 0.1 to 48 months). Mixed-breed dogs were at a significantly lower risk for glaucoma, compared with other breeds. Eyes with IOL placement were at a significantly lower risk for glaucoma, compared with eyes without IOL placement. Eyes with hypermature cataracts were at a significantly higher risk for glaucoma, compared with eyes with mature or immature cataracts.

Conclusions and Clinical Relevance—Multiple factors appear to contribute to the onset of glaucoma in dogs after cataract surgery. Complications prohibiting IOL placement during cataract surgery may lead to a high risk of glaucoma development. (J Am Vet Med Assoc 2000;216:1780–1786)
