Pruritus possibly associated with a portosystemic shunt in a bichon frise puppy.

A bichon frise puppy was presented with generalized pruritus. At 22 weeks, a portosystemic shunt was diagnosed. Correction of the shunt led to resolution of the pruritus.

Therapeutic options for cognitive decline in senior pets.

Many treatment options are now available for pets with age-related cognitive dysfunction, including drugs, nutritional supplements, and diets. This article describes the theory, evidence of efficacy, and potential neuroprotective effects of products used to treat cognitive dysfunction. Cognitive dysfunction is a diagnosis of exclusion, because many painful conditions and health problems may present with similar signs.

Underlying medical conditions in cats with presumptive psychogenic alopecia.

Objective: To identify underlying medical conditions in cats with a presumptive diagnosis of psychogenic alopecia.

Design: Case series.

Animals: 21 adult cats referred with a presumptive diagnosis of psychogenic alopecia.

Behavior problems in geriatric pets.

Aging pets often suffer a decline in cognitive function (eg, memory,learning, perception, awareness) likely associated with age-dependent brain alterations. Clinically, cognitive dysfunction may result in various behavioral signs, including disorientation; forgetting of previously learned behaviors, such as house training; alterations in the manner in which the pet interacts with people or other pets;onset of new fears and anxiety; decreased recognition of people, places, or pets; and other signs of deteriorating memory and learning ability. Many medical problems, including other forms of brain pathologic conditions, can contribute to these signs.

Therapeutic agents for the treatment of cognitive dysfunction syndrome in senior dogs.

With increasing age, dogs develop a form of neurodegenerative disease which has many similarities to age related cognitive impairment and Alzheimer's disease in humans. A decline in learning and memory can be demonstrated in dogs beginning as young as 7 years of age using a variety of neuropsychological tests. However, clinical cases of cognitive dysfunction syndrome are seldom identified until the age of 11 years or older.

Effects of clomipramine on cats presented for urine marking.

Twenty-five cats exhibiting at least four episodes of vertical urine marking per week were assessed. Following a medical workup, a 4-week clomipramine trial was instituted, using a mean dose of 0.54 mg/kg per os q 24 hours.

Geriatric behavioral problems.

Behavior problems in older pets may be due to many of the same causes as in younger pets. However, the effects of aging on the pet's body may cause a dramatic decline or deterioration in organ and sensory function, which may have a profound impact on the pet's behavior. A decline in cognitive function may also afflict older pets, in many instances due to the occurrence of Alzheimer's disease brain pathology, especially beta amyloid plaque formation.

Feline scratching and destruction and the effects of declawing.

Scratching is an inherited, normal behavior in cats that is used as a visual and olfactory territorial mark and as a stretching exercise for the forelegs. In addition, it serves to condition the claws by removing the old, worn-out external sheath and exposing the healthy, new claw. When scratching occurs indoors, it often is disruptive and undesirable unless it can be directed to an acceptable object such as a scratching post.
