Plain-English summary
A group of English Setter puppies in the UK were tested for congenital sensorineural deafness (CSD) to see how common it was and if certain traits affected their hearing. Out of 447 puppies, 95.5% had normal hearing, while 3.6% were found to be unilaterally deaf (hearing in one ear) and 0.9% were bilaterally deaf (hearing in both ears). The study found that female puppies were more likely to be deaf than males, and those with parents of unknown hearing status had a higher risk of deafness. This information can help breeders and owners be more aware of the risks associated with hearing issues in English Setters.

Abstract
BACKGROUND: The English setter (ES) is predisposed to congenital sensorineural deafness (CSD). CSD prevalence and association with phenotype in the UK ES population are previously unreported. METHODS: The database of the authors' institution was searched for ES puppies undergoing brainstem auditory evoked response (BAER) testing for CSD screening (2000-2018). Inclusion criteria were BAER performed at 5-10 weeks of age, testing of complete litters and available phenotypic data. The age, sex, presence of patches at birth, coat colour, iris colour, hearing status and BAER-determined parental hearing status of each puppy were recorded. Multivariable binary logistic regression was performed to determine the significance of these variables as predictors for the likelihood of puppies being unilaterally or bilaterally deaf. RESULTS: Inclusion criteria were met for 447 puppies. Hearing was bilaterally normal in 427 (95.5 per cent) puppies. The prevalence of unilateral and bilateral CSD was 3.6 per cent and 0.9 per cent, respectively. Females were 3.3 times more likely to be deaf than males, and puppies with both parents of unknown hearing status were 4.6 times more likely to be deaf than those with at least one normal parent. CONCLUSION: The prevalence of CSD was 4.5 per cent, with female puppies and those with two parents of unknown hearing status at greatest risk.
