Plain-English summary
A six-month-old Pomeranian was brought to the vet because it had a bluish tint to its skin (cyanosis) since it was a puppy. After thorough testing, including X-rays and heart evaluations, no major heart or lung issues were found. The vet then suspected a problem with the puppy's blood and diagnosed it with methemoglobinemia, a condition where the blood can't carry oxygen properly due to an enzyme deficiency. Treatment options were discussed to manage the condition and improve the puppy's health.

Abstract
A six-month-old Pomeranian was referred for evaluation of cyanosis. The puppy had been cyanotic since it was acquired at six weeks of age, but otherwise appeared normal. Diagnostics were aimed at the most common causes (i.e., congenital defects in the cardiovascular and respiratory systems) of cyanosis in a juvenile animal. No clinically significant abnormalities were detected on evaluation of thoracic radiographs, echocardiogram, cardiac color-flow Doppler examination, or blood gases. At this point, a dysfunction in hemoglobin was considered as a possibility. Methemoglobinemia due to deficiency of methemoglobin reductase enzyme was diagnosed based on a specific assay.
