Clinico-pathological Studies on Atopic Dermatitis in Dogs

Occurrence of allergic dermatitis in dogs with special reference to canine atopic dermatitis in Kerala

“…This observation was in accordance with the findings of Sharma et al (2015), who reported CAD in 63.8 per cent of male dogs which is on par with 63.5 percent of affected male dogs in the present study. This was in contrary to the observations made by Shaw et al (2004) and Brar et al (2017), who reported a similar distribution of CAD in both genders. Favrot et al (2010) noticed no gender predilection for atopic dermatitis in a fairly large population of atopic dogs, but observed some gender predisposition associated with certain breeds like Labrador retrievers, where more females were affected and vice versa for Boxer breed of dogs, in contrary to the observation of male predominance in Labrador and other breeds in the present study.…”

“…In the current study, a higher incidence of atopic dermatitis was found in dogs below 3 years of age (66.7 per cent), followed by >5 years (17.5 per cent) and age group >3 to 5 years (15.8 per cent). The present finding was in accordance with Griffin and De Boer (2001), Favrot et al (2010) and Brar et al (2017), who reported a higher occurrence of atopic dermatitis in dogs below 3 years of age followed by older dogs. Even though the onset of atopic dermatitis was more common between six months to three years, the disease was also observed in dogs below six months and above seven years of age (Saridomichelakis et al, 1999).…”

“…This was in contrary to the findings of Sharma et al (2015), who recorded highest occurrence rates for atopic dermatitis followed by flea allergy dermatitis and contact allergy dermatitis in a study investigating occurrence pattern of allergic dermatitis in dogs of Jammu, India. The occurrence rate of atopic dermatitis in the study period was 25.7 per cent of the allergic dermatitis cases recorded, which was in accordance with the findings of Brar et al (2017), in a study conducted in Ludhiana, India. However, the occurrence rate of atopic dermatitis was 3.1 per cent among the total dermatological cases presented during the study period.…”

“…Out of 63 dogs diagnosed with atopic dermatitis, Labrador (55.6 per cent) dogs were more prone to atopic dermatitis, followed by Beagle (14.3 per cent), Pomeranian (9.5 per cent), Shih Tzu (6.3 per cent), Pug (4.8 per cent), Pit bull (3.2 per cent), and, 1.6 per cent each for German Shepherd, Dachshund, Rottweiler and Golden Retriever (Table 4). Higher incidence of atopic dermatitis in Labrador breeds followed by other breeds was observed by Brar et al (2017), with the Labrador breeds representing less than fifty per cent in their study. Schick and Fadok (1996) observed a strong predilection for atopic dermatitis with Labrador retrievers and Golden retriever breeds, in a study conducted in the United States, whereas Jaeger et al (2010) reported that breed predilections for this disease may vary with geographic location.…”

“…In the present study, the occurrence of allergic dermatitis was 13 per cent, whereas Sharma et al (2015) reported 9.23 per cent in their study, among the various dermatological affections recorded. The higher number of allergic dermatitis cases recorded in this study was during the monsoon season, ie., during September and October as reported by Brar et al (2017). The reason might be due to favourable environment, which facilitate more moisture accumulation in the skin of animals, resulting in enhanced precipitation of dermatological affections as suggested by Dimri and Sharma (2004).…”
