Background and Aim: Rabbits often experience skin diseases. The beneficial effects of plant extracts and essential oils are well known in other species, but the properties of these natural ingredients have not been evaluated in rabbits in vivo. The objective of the current study was to evaluate the effect of a topical, commercial solution made of essential oils, plant-extracted polyunsaturated fatty acids, and Vitamin E on rabbits suffering from skin problems. Materials and Methods: Thirty New Zealand rabbits (no sex distinction) were included in this study, with an average weight of 2–3 kg. The rabbits were divided into two groups: The first group was treated with a topical solution made from natural ingredients, and the second was a control group. The rabbits' hair and skin conditions were evaluated on days 1, 14, 28, and 35 after treatment. Data were analyzed using a Kruskal–Wallis range test. Results: Significant differences were determined in terms of glossy hair variability on days 28 and 35 (p≤0.0001). On days 14-35, hair loss was determined to have reduced (p=0.001), and flaking and odor improved in the treatment group, showing increased scores and significant differences (p=0.0001). By contrast, the control group showed stable overall skin and hair score and an increase in the dryness score. Conclusion: The topical application of essential oils and polyunsaturated fatty acids with Vitamin E was able to improve hair shine and skin hydration and reduce flaking, bad odor, and hair loss, improving the general, and cutaneous aspect of rabbits.

Rabbits (Oryctolagus cuniculi) are very popular as pets. However, problems of otitits caused by Psoroptes cuniculi are one of the main reasons to visit the veterinarian. Isoxazolines are an alternative treatment to treat this mite, and therefore, an evaluation of the effectiveness of oral afoxalaner with milbemycin oxime in rabbits infected with P. cuniculi was carried out. Nineteen rabbits, of New Zealand breed, with otitis due to an infection with P. cuniculi, were treated, whereas six rabbits were left untreated and formed the control group. The ear canals of each individual were examined, through the collection of otic exudate samples with cotton swabs. These were visualized under the microscope to identify the ectoparasite. Each animal was treated with a single oral dose of 2.50 mg / kg of afoxolaner, and 0.50 mg / kg of milbemycin oxime. Clinical signs and lesions associated with the infection, such as the presence of detritus, cerumen and / or scabs, and erythema, were evaluated. After receiving the treatment, all the lesions were classified as: mild, moderate and intense, with a visual analog scale. A week after providing medication, there was a decrease in the lesions of the group treated with Nexgard Spectra®, without further topical or systemic treatment. The decrease was gradual in the treated group and no recurrence was detected of P. cuniculi infection in both ears. Thus, the administration of a single oral dose of afoxolaner with milbemycin oxime was effective for the treatment of P. cuniculi infection in rabbits.
