Familial nephropathy in cocker spaniels.

A clinical diagnosis of chronic renal failure associated with nephron atrophy and fibrosis was made in 4 blue roan Cocker Spaniels. The lesion was considered to be the result of a primary glomerulopathy. All dogs were closely related. The findings were similar to those previously described for renal cortical hypoplasia. On the basis of the morphological findings and genetic characteristics, the use of the more appropriate term, familial nephropathy is encouraged.
