Dogs, both pedigree and cross breeds, can be affected with genetic problems. Those known to sometimes occur in English Setters can include congenital deafness, which was reported as affecting 12.4 percent of the 701 English Setters tested by the Louisiana State University in 2010. As at 2013, there has not been any detailed research on this condition undertaken in the UK; autoimmune thyroiditis, which was shown to affect 26.2 percent of 747 English Setters examined between January 1974 until December 2012 in an Orthopedic Foundation for Animals listing; canine hypothyroidism; elbow dysplasia; and allergies, which can include some sensitivity to certain food ingredients and also skin conditions, are known to occur.
