Abstract
A four-year-old intact female American Pit Bull Terrier was brought to the hospital for unresolved weight loss, complete loss of fur, and persistent skin ulcers. Upon presentation, the patient showed severe dehydration, emaciation, and bilateral cataracts despite having reportedly good appetite and responsive behavior. Further examination and work-up diagnosed the patient with diabetic ketoacidosis – a complicated form of diabetes mellitus where insulin deficiency causes increased lipolysis and ketosis, resulting in ketonemia and metabolic acidosis. Multiple glucose curves and adjustments to insulin therapy led to the treatment of DKA and the successful management of diabetes. In the initial 5 months of treatment, the patient showed gradual but consistent improvement in clinical signs and quality of life. This case report shows the consequences and risks of having a severely diabetic canine patient remain undiagnosed and without appropriate insulin therapy. Highlighted through discussion and photos are the reversibility of clinical signs caused by the harmful effects of hyperglycemia, and the successful management of DKA and DM without hospital confinement.
