Congenital and Hereditary Disorders of the Kidney

Structural Anomalies of the Kidney RENAL AGENESIS Renal agenesis is the complete absence of one or both kidneys. Bilateral renal agenesis is fatal and is a cause of early death in puppies and kittens (). Unilateral renal agenesis is more frequendy observed in puppies and kittens than is bilateral agenesis (). Unilateral renal agenesis may affect either kidney and is usually accompanied by ipsilateral ureteral agenesis. The etiopathogenesis of renal agenesis in dogs and cats is uncertain. A familial predisposition for renal agenesis in beagles, Shetland sheepdogs, and Doberman pinschers supports a genetic basis for the anomaly (Table 17-1). Unilateral renal agenesis may remain clinically silent, provided the contralateral kidney undergoes sufficient compensatory change to maintain normal hemostasis. Clinical findings may include an inability to palpate both kidneys or to detect a kidney by ultrasonography or contrast urography. Because of close associations in the development of the urogenital system, findings of abnormal or absent vas deferens, epididymal tails, or uterine horns at the time of castration or ovariohysterectomy should arouse suspicion of concurrent unilateral renal agenesis. Because unilateral renal Read more […]

Anatomy Of The Dog: What is a Breed

A few months ago, the United Kennel Club added nine breeds, to its registry, bringing its total to 160. Last month, the American Kennel Club announced the addition of the American Kennel Club announced the addition of the American Eskimo to its miscellaneous group, the first step towards official recognition as an AKC breed. The new UKC breeds are Petit Basset Griffon Vendeen, Canaan Dog, English Toy Spaniel, Finnish Spitz, Greater Swiss Mountain Dog, Manchester Terrier, Polish Owczarek Nizinny, Tibetan Spaniel and Shiba, all but the Nizziny are recognized by the AKC, some of them for many years, and AKC’s newest, the American Eskimo, has been a UKC breed for a long time. Both registries seem to be in race to add new breeds to their lists, a race that some critics say is an effort to increase the treasuries of both organizations. This rush, along with the apparent whimsical assignment of breed status in some cases, an increase in breed-specific laws in the last few years, and the call by animal rights advocates for a ban on breeding pure bred dogs, has caused some to wonder about the definition of breed. So what is a breed? Webster’s Desk Dictionary of the English Language defines a breed as “a homogeneous grouping Read more […]
