A 10-year-old 7.6-kg (16.7-lb) spayed female Pekingese was referred for evaluation because of progressive clinical signs including dull mentation, circling to the right, a right-sided head turn, head pressing, and, more recently, coughing, vomiting, anorexia, and melena. Empirical treatment with dexamethasone sodium phosphate, an antimicrobial, and a gastroprotectant was unsuccessful in resolving the clinical signs. Results of serum biochemical analysis and a CBC prior to referral revealed mildly high alkaline phosphatase activity and a stress leukogram.

A 5-year-old 25-kg (55-lb) castrated male Siberian Husky was evaluated because of sudden onset of circling 7 days earlier. Muscle atrophy of the right temporalis muscle became evident 5 days prior to the scheduled appointment. Bilateral corneal dystrophy and keratoconjunctivitis sicca of the right eye were diagnosed by the referring veterinarian approximately 1 month prior to the onset of the clinical signs.
During physical examination, the dog was quiet, alert, and responsive. No abnormalities were detected during auscultation of the heart and lungs; heart and respiratory rates were within reference limits. The mucous membranes were pink and slightly dry with
A 9-week-old 5.18-kg (11.4-lb) male Border Collie was referred for evaluation of right conduction deafness and reduced hearing of the left ear, diagnosed 3 weeks earlier via brainstem auditory evoked response (BAER) testing with click and bone stimulation. The breeder had requested BAER evaluation of the entire litter at 48 days of age because of the breed's predilection for sensorineural deafness. In this dog, BAER testing of the right ear initially revealed deafness. However, bone stimulation testing revealed normal auditory responses consistent with right ear conduction deafness. Possible causes that were considered included structural middle ear disease or a lesion
An 8-year-old 6.4-kg (14.1-lb) neutered male Papillion was referred for neurologic evaluation of a sudden worsening of cervical hyperesthesia 3 days prior. Severe cervical hyperesthesia was first noted approximately 9 months prior. The referring veterinarian suspected cervical intervertebral disk disease and offered referral, but the owners opted for medical management at that time, which included administration of prednisolonea (0.4 mg/kg [0.18 mg/lb], PO, q 12 h for 3 months) and methocarbomalb (19.5 mg/kg [8.86 mg/lb], PO, q 8 h for 9 months), cage rest, and intermittent laser therapy. Over a 3-month period, medications were given inconsistently.
