Health matters
The Glen of Imaal Terrier generally suffers from few congenital or hereditary diseases, certainly no more than your average breed. However, the Glen does have a primary congenital & hereditary condition that has been diagnosed in the breed; late onset PRA, a degenerative eye disease that eventually leads to blindness and must be diagnosed as soon as possible, there is no effective treatment but early diagnosis will render information as to suitability for breeding, with affected dogs being removed from any potential breeding programmes - it is recommended that all Glens be eye-tested yearly.

Glens can be prone to hip dysplasia as is the case with many breeds.

A common problem among all terriers, and the Glen is no exception, are skin irritations. In most cases, the eruptions are a result of flea allergies. There appears to be a genetic predisposition to such allergic reactions. Your breeder can provide information about the history of this problem, if such a problem exists, in the lines of his/her breeding programme.
