Familial progressive nephropathy in young Bull Terriers

Abstract

The clinical, clinicopathological and pathological findings are described in three Bull Terrier bitches with advanced renal disease. The bitches were less than four years old and showed variable presenting signs but anorexia, lethargy and polydipsia were the most frequent. All three dogs were azotaemic and isosthenuric. Urinary protein was measured in two of the three cases. Both were proteinuric. At necropsy all dogs had shrunken kidneys. Histological examination revealed nephron loss, atrophy of glomerular tufts, interstitial fibrosis, and mineralisation of basement membranes.

The progressive renal disease in these dogs was similar to the condition reported in Bull Terriers in Australia, and is probably familial and inherited.
