Renal disease affecting 3 male and 1 female English Cocker Spaniels was studied. Clinical features of the disease included proteinuria and progressive deterioration of renal function. Dogs were 11 to 27 months old when euthanized because of severe chronic renal failure. Grossly, the renal cortices were thin. Light microscopic evaluation revealed diffuse glomerular disease characterized by mesangial thickening, glomerular fibrosis, periglomerular fibrosis, and glomerular obsolescence. Based on these clinical and pathologic features, familial nephropathy of English Cocker Spaniels was suspected despite the fact that the individual dogs were not closely related. On transmission electron microscopy, a distinctive ultrastructural lesion was observed in the glomerular basement membranes (GBM) of all dogs. The GBM exhibited extensive thickening, multilaminar splitting, and fragmentation. Electron dense deposits, suggestive of immunocomplex glomerular disease, were notably absent. A similar ultrastructural GBM lesion is found in human beings and Samoyeds with hereditary nephritis, diseases caused by mutations in the type IV collagen genes. Familial nephropathy in English Cocker Spaniels may be a form of hereditary nephritis caused by a mutation in one of the collagen IV genes.

Juvenile nephropathy has been documented in many breeds. Two related Pembroke Welsh corgi puppies presented at three and five months of age, respectively, for evaluation of lethargy, diarrhoea, poor body condition, polyuria and proteinuria. Based upon the clinical presentation, urinalysis and serum biochemistry, chronic renal failure was diagnosed. Renal histopathology was consistent with juvenile nephropathy, revealing lesions similar to the juvenile renal disease of dobermann dogs. To the authors' knowledge, this is the first report of juvenile nephropathy in related Pembroke Welsh corgi dogs. Familial nephropathy should now be considered as a differential diagnosis in cases of young Pembroke Welsh corgi dogs presenting with clinical signs indicating renal failure.
