Atopy/allergy derived dermatological problems are common problems in canine
medicine today and hard to diagnose correctly. The etiology is unknown but
several theories are proposed; e g abnormal immunity due to too good hygiene"
or non-physiological diet, deranged microbiota, abnormal absorption, or lack of
key nutrients in the food. As symptoms often are helped by changing the diet to
raw food, we hypothesized that raw food intake at a young age might decrease
the incidence of atopy/allergy in dogs.
An early data (n=3475) of the DOGRISK owner questionnaire was used for
this study (www.ruokintakysely.fi).
It includes questions about the dog's descriptives, diseases, environmental
factors and nutrition at different life stages. The dogs suffering from
atopy/allergy were chosen as the case group (n=150) whereas a double amount of
healthy dogs were chosen as a control group (n=300). Associations between
diseases and 54 food items served at ages 2-6 months as well as >6-18 months
were analyzed using cross-tabulation and Pearson Chi-square test.
The sample (n=450) was not significantly different from the whole data
(n=3475), except for having more neutered dogs and less families where the dog
was the only dog. The diet at 2-6 months of age showed a significant
association between the following raw food items and being free from
atopy/allergy: raw diets, -offal, -meat, -bone, -cartilage, -tripe, -fish, -egg,
-vegetables, -berries, and drinking from outdoor puddles (p=<0.001-0.013)
whereas dry dog food and skin chewing bones significantly associated with an
increase in atopy/allergy (p=0.004-0.033). There were no other significant
associations between food items and atopy/allergy (Table 1).
Significantly more males, white coated animals, dogs with mothers that suffered from atopy/allergy and dogs that had spent less time outside, also suffered from the disease. However, in logistic regression models raw meat stayed as a significant item that decreased atopy/allergy.
This study proposes a decrease in the incidence
of atopy/allergy type of disease in dogs that eat raw animal proteins. More
complex analyses should be performed, looking for more confounding variables.
If the results still stand, clinical studies should be performed to verify
It seems that bone
and raw food (BARF) at a young age has a positive influence on atopy/allergy
incidence in dogs. Already when 20 % (1/5) of the diet is BARF, there starts to
be more healthy dogs per group (Fig. 3). In this study both raw proteins and
raw vegetables and berries were saving the dog from atopy/allergy type of
disease whereas typical commercial dry products seemed to increase the risk for
this disease. In the logistic model of suffering from this diseases or not,
eating raw meat as well as raw bone and cartilage gave the strongest
association of the food items.
