The results, presented at the European Respiratory Society's International Congress in Munich, lend support to the "hygiene hypothesis" that suggests too much cleanliness early in life can increase susceptibility to allergies.
Lead researcher Dr Christina Tischer, from the Helmholtz Zentrum Munchen Research Centre, said the results supported earlier research.
"Previous studies have suggested that microbes found in rural settings can protect from asthma. An animal skin might also be a reservoir for various kinds of microbes, following similar mechanisms as has been observed in rural environments.
"Our findings have confirmed that it is crucial to study further the actual microbial environment within the animal fur to confirm these associations."
