“…The suggestions for inheritance of deafness in Dalmatians include a dominant gene with incomplete penetrance, double dominant genes, or multifactorial recessive genes (Strain et al, 1992). Previous studies have identified statistically significant associations between deafness and a blue iris colour and white coat pigmentation (Strain, 2004;Platt et al, 2006). In the present article the occurrence was higher in dogs with one or two blue eyes.…”

“…This condition is widespread, occurring in approximately 80 dog breeds (Strain, 2004). About 20% of Dalmatian dogs have unilateral deafness, and 10% have bilateral deafness (Wood and Lakhani, 1998).…”

“…While bilateral deafness may be obvious to the owner of an affected animal, unilateral deafness is exceedingly difficult to appreciate clinically because the animal can compensate for the disability (Strain, 1996;Strain, 1999;Muhle et al, 2002;Strain, 2004). Indeed, it is stated that animals with unilateral deafness cannot be distinguished from healthy animals by their owners using behavioral tests (Muhle et al, 2002).…”

The brain stem auditory-evoked potential (BAEP) is an electrophysiologic test that detects and records the electrical activity in the auditory system from cochlea to midbrain, generated after an acoustic stimulus applied to the external ear. The aim of this study is to obtain normative data for BAEP in Dalmatian dogs in order to apply this to the evaluation of deafness and other neurologic disorders. BAEP were recorded from 30 Dalmatian dogs for a normative Brazilian study. Mean latencies for waves I, III, and V were 1.14 (±0.09), 2.62 (±0.10), and 3.46 (±0.14) ms, respectively. Mean inter-peak latencies for I-III, III-V, and I-V intervals were 1.48 (±0.17), 0.84 (±0.12), and 2.31 (±0.18) ms, respectively. Unilateral abnormalities were found in 16.7% of animals and bilateral deafness was seen in one dog. The normative data obtained in this paper is compatible with other published data. As far as we know this is the first report of deafness occurrence in Dalmatian dogs in Brazil.

“…We found unilateral deafness in 1 and bilateral deafness in 2 Boxers. Other studies that have evaluated the incidence of deafness showed a higher incidence of unilateral deafness compared to bilateral deafness in different breeds, such as Border Collies (2.3% unilateral and 0.5% bilateral) (Platt et al 2006), Bull Terriers (9.9% unilateral and 1.1% bilateral) (Strain 2004), Australian cattle dogs (12.2% unilateral and 2.4% bilateral) (Strain 2004), English Setters (12.7% unilateral and 2.4 bilateral) (Strain 1996) and English Cocker Spaniels (7% unilateral and 1.8% bilateral) (Strain 1996). The fact that this report found more bilateral deafness than unilateral, when other published reports, studying other breeds, found a higher prevalence of unilateral than bilateral, is certainly the result of the small sample size.…”

“…Congenital hereditary hearing loss is a widespread problem occurring in approximately 80 breeds of dog (Strain 2004), and it is more commonly observed in dogs with white pigmentation (Muhle et al 2002). In most dog breeds, inherited congenital sensorineural deafness results from perinatal degeneration of the stria vascularis, which appears to result from the local absence of functional melanocytes (Strain 1996).…”

RESUMO.-[Potencial evocado auditivo de tronco encefálico em cães da raça Boxer.] O potencial evocado auditivo de tronco encefálico (PEATE) tem sido amplamente utilizado com diferentes finalidades na prática veterinária e é comumente usado para identificar a surdez hereditá-ria e a presbiacusia. No presente estudo, 43 cães da raça Boxer foram pelo teste PEATE. Foi diagnosticada surdez em 3 cães (2 bilaterais e 1 unilateral), e 40 Boxers foram usados no estudo normativo incluindo avaliação da influência da idade no PEATE. Os animais foram divididos de acordo com a idade em 2 grupos de 20 Boxers cada. A idade media foi 4,54 anos (variação de 1-8) no grupo I e 9,83 anos (variação de 8,5-12) no grupo II. A latência media das ondas I, III e V foram: 1,14 (±0,07); 2,64 (±0,11) e 3,48 (±0,10) ms no grupo I; e 1,20 (±0,12); 2,73 (±0,15) e 3,58 (±0,22) ms no grupo II, respectivamente. A latência media para os intervalos I-III, III-V e I-V foram 1,50 (±0,15); 0,84 (±0,15) e 2,34 (±0,11) ms no grupo I; e 1,53 (±0,16); 0,85 (±0,15) e 2,38 (±0,19) ms no grupo II, respectivamente. As latências das ondas I e III foram estatisticamente diferentes entre os grupos I e II. Não foram observadas diferenças estatísticas entre os dois grupos para os intervalos I-III, III-V e I-V. De acordo com a revisão realizada, este é o primeiro estudo normativo de BAEP realizado em cães da raça Boxer. Brainstem auditory-evoked potential (BAEP) has been widely used for different purposes in veterinary practice and is commonly used to identify inherited deafness and presbycusis. In this study, 43 Boxer dogs were evaluated using the BAEP. Deafness was diagnosed in 3 dogs (2 bilateral and 1 unilateral) allowing the remaining 40 Boxers to be included for normative data analysis including an evaluation on the influence of age on the BAEP. The animals were divided into 2 groups of 20 Boxers each based on age. The mean age was 4.54 years (range, 1-8) in group I, and 9.83 years (range, 8.5-12) in group II. The mean latency for I, III, and V waves were 1.14 (±0.07), 2.64 (±0.11), and 3.48 (±0.10) ms in group I, and 1.20 (±0.12), 2.73 (±0.15), and 3.58 (±0.22) ms in group II, respectively. The mean inter-peak latencies for the I-III, III-V and I-V intervals were 1.50 (±0.15), 0.84 (±0.15), and 2.34 (±0.11) ms in group I, and 1.53 (±0.16), 0.85 (±0.15), and 2.38 (±0.19) ms in group II, respectively. Latencies of waves I and III were significant different between group I and II. For the I-III, III-V and I-V intervals, no significant differences were observed between the 2 groups. As far as we know, this is the first normative study of BAEP obtained from Boxer dogs.
