Insulin Resistance Due to Periodontal Disease in an Old Diabetic Female Poodle

The purpose of this work was to report a clinical case of a spayed, 13-year-old diabetic poodle on insulin therapy with insulin resistance and poor diabetes control secondary to severe periodontitis. Prior to establishing the periodontal surgical approach, the insulin dose needed to be increased to stabilize the patient. Periodontal treatment included the extraction of 19 teeth. After periodontitis treatment, the insulin dose could be reduced to the previous effective dose. To our knowledge, this is the first case report of insulin resistance due to periodontal disease in dogs.
