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 […]

Intention tremors due to cerebellar disorders

Tremors that occur when an animal intends to move in a goal-orientated activity are most often the result of cerebellar disease (). Degenerative diseases Cerebellar cortical degeneration Cerebellar cortical degeneration, also termed cerebellar abiotrophy, is usually an inherited disease in dogs () with few reports in cats. Primary cerebellar cortical degeneration refers to degeneration and loss of Purkinje cells, molecular cells and granule cells. Clinical signs: These diseases are recognized syndromes in American Staffordshire Terriers, American Pit Bull Terriers, Kerry Blue Terriers, Gordon Setters, Rough-coated Collies, Border Collies, Brittany Spaniels, Bullmastiffs, Old English Sheepdogs and occur rarely in Samoyeds, Airedales, Finnish Harriers, Labrador Retrievers, Golden Retrievers, Beagles, Cocker Spaniels, Cairn Terriers, Great Danes, Scottish Terriers and others (). Clinical signs usually begin between 3 and 12 months of age. However, a subset of adult onset diseases occur with signs starting from 2-8 years of age in the Brittany Spaniel (), Gordon Setter (), Old English Sheepdog (), American Staffordshire Terrier () and Scottish Terrier (). Other signs of cerebellar disease that accompany cerebellar Read more […]

Canine Kidney Diseases

Diseases Of Different Organs Canine kidney diseases can occur for a variety of reasons, including the presence of tumours in the body, heart failure, bladder stones, or shock following a severe accident. Dr Bush explains how the kidneys work, how they can be affected by disease, and discusses the treatments available to dogs. Understanding the nature of kidney diseases in the dog requires first of all a little knowledge of how the kidneys function. Normal kidneys perform a number of important tasks, espeially, 1) Removing from the body the waste products of metabolic processes (excretion), particularly those resulting from the breakdown of proteins such as urea. 2) regulating the amounts of “salts”, for example, electrolytes such as sodium and potassium, and water in the body. If there is an excess of any of these, the surplus is excreted; if in short supply, excretion is reduced as far as possible so that the substance is conserved. This excretion of substances is achieved by producing urine, the composition of which can be varied. In addition, although not germane to a general consideration of renal disease, the kidneys also control the degree of acidity or alkalinity within the body, secrete hormones affecting blood Read more […]

Ringcraft

The Changing Role of Ring Stewards As Shows Become Bigger And More Complex, There is An Increasing Need For Training And Experience Among Ring Stewards. The History of Ring Stewarding: It would be wonderful to write about the noble and ancient position of the ring steward. Unfortunately, no Ring Steward’s Hall of Fame exists, nor is there a “History of Ring Stewards Around the World.” Suffice it to say that ring stewards have probably been around for as long as there have been dog shows, but it seems the details of the job have changed over the years. A bit of research suggests the modern ring steward should be grateful. Fifty years ago it was the practice for ring stewards to travel from the ring to the benching area to locate the dogs to be judged in the next class, along with corralling the handlers, who may have been somewhere else. Additionally, it was the steward’s job to attach the armband to each exhibitor as they entered the ring, then remove all armbands after the class was judged and retain the winners’ armbands for Winner’s judging. Believe it or not, there may actually be a way to trace the origin of the practice of “grab some friends and make them ring stewards for the day.” An article appearing in the Read more […]
