Of course, there are many variations of normal between individuals. Of course, there are many variations of normal between individuals. The results of hind leg spinal reflex tests, such as the patellar reflex, are more reliable than those of the front legs. Also it is important to recognize that the collapse episodes we see in dogs with BCC are very different from those associated with actual heat stroke. Evans J, Levesque D, Knowles K, et al. Dehydration in dogs is a common problem, and it can be serious if not treated. Biceps reflex evaluates C6 to C8 spinal nerves and, peripherally, the musculocutaneous nerve (Figure 8). Loss of muscle around the torso or hind legs can indicate damage to a nerve associated with that muscle. Dogs that overheat can become dehydrated because they are sweating and losing fluids through panting. These include tests of various reflexes, muscle function and control, and posture and gait. Physical exam should include a complete otoscopic exam and complete neurological examination to determine if the patient localizes to peripheral or central disease. Each dog was given 19 tests in eight She also has a special interest in non-invasive advanced imaging procedures of the brain and spinal cord, specifically high-field MRI. A careful history should be taken, including rate and duration of onset, whether the signs have progressed since onset, medications administered, diet, travel history, and existence of any other comorbidities. Hopping (thoracic limb): Place one hand under the abdomen to life the pelvic limbs from the ground; the other hand folds a thoracic limb back along the chest while pushing the animal toward the standing limb. Heart rate: Typically elevated in both dogs and cats at the beginning of most critical illnesses (may also be stress related from being in the hospital).

An unusually high amount of protein in the cerebrospinal fluid may indicate encephalitis (inflammation of the brain), meningitis (inflammation of the covering of the brain), cancer, or a compressive injury of the spinal cord. Computed tomography (CT) and magnetic resonance imaging (MRI) scans can also help evaluate changes in bone structure, internal bleeding, abscesses, inflammation, and certain nervous system cancers. All of the factors contributing to the tendency for an affected dog to collapse on a given day (excitement, heat, intensity of exercise) have not been determined. Enophthalmos, which is often present, is not appreciated in this photograph. Hopping (pelvic limb): One hand under the chest lifts the thoracic limbs off the ground; the other hand, placed by the femur, lifts one pelvic limb off the ground and pushes the patient toward the standing limb. How did the clinical signs occur (acute versus insidious onset)? Metronidazole administration can cause central vestibular or cerebellar dysfunction in dogs, typically following chronic administration of doses that This is similar to a dull animal but responses to stimuli are inappropriate. Palpation: When palpating the spine, use the free hand to support the area being palpated and prevent the patient from falling or sitting down. Vomiting or having diarrhea contribute to the signs of dehydration in dogs because they are losing fluids faster than they can take them in. No abnormalities have been detected in serum electrolytes (sodium and potassium), blood sugar, blood cortisol, ability to ventilate, or heart rhythm that can explain the collapse in dogs with BCC. The paw replacement test (previously called conscious proprioception) and hopping test are the assessments most frequently performed. Patella reflex: Slightly flex the stifle and tap the patella tendon with the pleximeter. be described, including compulsive behavior, agitation, aggression, and dementia.
