“…The wild type has erect and mobile pinna due to three interdigitating auricular cartilages that provide a scaffold for the vertical ear canal 9, 10 . In contrast, lop-eared breeds have 3-5mm of soft tissue between the proximal acoustic meatus cartilage ring and the tragal cartilage of the distal ear canal, causing the pinna to fold and become pendulous 10, 11 .…”

“…Lop-eared rabbits have increased stenosis (narrowing) of their ear canals 9, 14, 15 . This, along with ear canal occlusion by the pinna, is believed by some veterinary professionals to reduce airflow and hinder expulsion of cerumen (or ‘earwax’) 10, 11, 14 . Cerumen accumulation at the base of the ear in lop-eared rabbits has been suggested as a predisposing factor for otitis externa, caused by bacterial or yeast overgrowths 11, 14, 16, 17 .…”

Mite infestation with Psoroptes cuniculi can also cause otitis externa, usually with extensive crusting of the pinna 10 .…”

This research aimed to assess whether rabbits having lop-ears is a welfare issue by investigating the occurrence of aural and dental pathology in lop-eared compared with erect-eared rabbits.Thirty rabbits (15 lop-eared and 15 erect-eared) from a rabbit-only rescue shelter were examined. An otoscope was used to visualise the ear canals and mouth. Samples were taken from each ear to examine for mites, bacteria and yeast. Medical records were also examined.Lop-eared rabbits showed statistically significantly more frequent ear canal stenosis, higher scores of cerumen and erythema, and more frequent potential pain response during ear examination, compared with erect-eared rabbits. We also found statistically significantly more frequent incisor pathology, molar overgrowth, molar sharpness, molar spurs and history of veterinary dental treatment in lop-eared compared with erect-eared rabbits. The effect sizes were often large. Age was not statistically significant between the lop- and erect-eared rabbit groups.Thus, lop-eared rabbits are at an increased risk of aural and dental pathology. This brings into debate the ethics of breeding and buying lop-eared rabbits, as they are more likely to suffer conditions that negatively impact welfare, such as pain, and potentially deafness and difficulty eating.

“…It is well reported in dogs, cats and rabbits (Fossum , Capello , Csomos et al . ), but it is rare in rodents (Jepson ). In fact, to our knowledge, this clinical case is the first report in a Guinea pig (Fig.…”
