Abstract

Abstract: Spay/neuter identification tattoos and ear-tipping are simple and cost-effective methods to minimize the likelihood of unnecessary anesthesia and surgery in companion animals or the misidentification of sexually intact animals. This study assessed training of sterilization identifiers in US and Canadian veterinary schools and practitioner compliance with guidelines for identifiers via surveys conducted in 2019. Faculty in all 34 schools responded to the survey, reporting that curricula included sterilization identifiers in 31% of lecture-based training, 75% of spay/neuter laboratory-based training, and 38% of clinical practice-based training. A total of 425 facilities performing spay/neuter reported frequency and technical aspects of sterilization identifiers in client-owned and unowned (shelter, rescue, trap-neuter-return) animals. Facilities encountering large numbers of animals of unknown background, performing a high number of surgeries, or with specialized spay/neuter training were significantly more likely to use identifiers. Only 5% of private practices tattooed all owned animals, and 21% tattooed all unowned animals. In contrast, 80% of shelters and 72% of spay/neuter clinics tattooed all owned animals, and 84% of shelters and 70% of spay/neuter clinics tattooed all unowned animals. Green was the most common tattoo color (97%); the most common placement was near or in the incision for female cats (99%), female dogs (99%), and male dogs (92%), and ventral abdomen in male cats (55%). Enhanced training and implementation of best practices described in professional guidelines for sterilization identifiers are needed throughout the veterinary industry to protect animals from unnecessary procedures and to prevent unintended litters in animals misidentified as previously sterilized. Highlights: Standard of care guidelines recommend visible identification of sterilized animals. Identification techniques are not consistently taught in veterinary schools. Only 5% of private practices tattooed all animals. More than 70% of shelters/high-volume spay/neuter practices tattooed all animals. Universal use of sterilization indicators is needed to avoid unnecessary surgery.
