Background Although 98% of the canine population is Dal‐positive, Dal‐negative dogs are more common in some breeds such as Doberman Pinschers (42.4%) and Dalmatians (11.7%), and finding compatible blood for these breeds may be challenging, given limited access to Dal blood typing. Objectives To validate a cage‐side agglutination card for Dal blood typing and determine the lowest packed cell volume (PCV threshold) at which interpretation remains accurate. Animals One‐hundred fifty dogs, including 38 blood donors, 52 Doberman Pinschers, 23 Dalmatians and 37 anemic dogs. Three additional Dal‐positive canine blood donors were included to establish the PCV threshold. Methods Dal blood typing was performed on blood samples preserved in ethylenediaminetetraacetic acid (EDTA) <48 hours using the cage‐side agglutination card and a gel column technique (gold standard). The PCV threshold was determined using plasma‐diluted blood samples. All results were read by 2 observers, blinded to each other's interpretation and to the sample's origin. Results Interobserver agreement was 98% and 100% using the card and gel column assays, respectively. Overall, the sensitivity and specificity of the cards were 86%‐87.6% and 96.6%‐100%, respectively, depending on the observer. However, 18 samples were mistyped using the agglutination cards (15/18 by both observers): 1 false‐positive (Doberman Pinscher), and 17 false‐negative samples including 13 anemic dogs (PCV range, 5%‐24%; median, 13%). The PCV threshold allowing reliable interpretation was determined to be >20%. Conclusions and Clinical Importance Dal agglutination cards are reliable as a cage‐side test, but results should be interpreted cautiously in severely anemic patients.

Background: Placement of a subcutaneous ureteral bypass (SUB) device is an effective method to relieve all causes of ureteral obstruction in cats. Complications involving migration within the gastrointestinal tract have been seldomly described. Objectives: To characterize transmural migration of SUB devices within the digestive tract in cats. Animals: Eleven migrated SUB catheters identified in 8 cats between 2017 and 2021. Methods: Retrospective review of medical records of cats with a SUB device in which migration into the gastrointestinal tract was identified. Results: The median time from SUB device placement to implant migration was 928 days (201-2298 days). Seven cats had obstruction of the SUB device and a positive urine culture at diagnosis. The migration was identified by ultrasound in 6/11, pre-operative contrast radiography in 2/2, and only at time of surgery in 3 SUB devices. All cats underwent surgical correction. Four nephrostomy and 7 cystotomy catheters migrated. Migration occurred into the duodenum (3/11), jejunum (7/11), and colon (1/11). SUB devices were removed in 7 cats and replaced in 2 cats, with Abbreviation: SUB, subcutaneous ureteral bypass.

A 12-year-old spayed female domestic shorthair cat was evaluated for a 3-week history of abdominal distension. Chyloabdomen secondary to pancreatic carcinoma was diagnosed. The cat was palliatively managed using rutin and a low-fat diet. The etiology, diagnosis and management of chyloabdomen are discussed.
