This review provides insight on potential host-specific factors that increase individual susceptibility to infection and transmission of bovine digital dermatitis. Digital dermatitis is increasing in prevalence within herds worldwide and yields economic losses for producers and welfare issues for animals. A total of 34 relevant studies were reviewed based on the inclusion criteria. A decrease in susceptibility to disease was found in animals with specific genomic and hoof characteristics, thus citing the importance of sire selection when designing a breeding program. Animals with superior health status that lacked co-morbidities and mounted immune responses to infection were less likely to develop disease. Primiparous cattle and those in peak production were more likely to develop lesions, as were over-or-under-conditioned Holstein–Friesian breeds. Cattle with superior hoof conformation and gait were poor hosts for bacteria and therefore less likely to develop and spread infection. The lowest risk of transmission of digital dermatitis occurred during the dry period and post peak lactation and cattle with advanced lesions contributed to the persistence of the disease within a herd. It is hoped that this review will help producers design breeding and management programs for their herds, and help veterinarians advise clients on the subject.
