A cutaneous form of canine leishmaniosis was diagnosed using molecular tools from a 10-years-old Chihuahua dog living in the Caribbean region. The critical health condition of the geriatric patient may have evolved to a fatal renal failure. This report is the first of a fatal case of leishmaniosis in a dog from the endemic region in Mexico.
