Applied Cytology

Buster, a 2-year-old, intact, male mixed-breed dog was adopted from a local shelter and presented to the veterinary clinic for health evaluation and neuter operation.

History. Vomiting initially occurred once per week but increased to twice per day during the 2 weeks before presentation.

A six-year-old, intact male German shepherd was presented to the veterinary hospital for lethargy, inappetence, and possible lameness for 5 days.

The dog lives in a rural environment and is exposed to cattle and horses. It has no notable previous medical history and is not on a heartworm-, flea-, or tick-control program. The dog is fed a generic dog food purchased from a local feed store. It enjoys frequent swims in a nearby river.

Otitis externa is one of the most common reasons dogs are presented to a veterinarian. Cytologic evaluations of ear swabs are crucial for assessment and management of recurrent ear infections.
