Allium spp. (A. cepa [onion], A. ampeloprasum var. porrum L. [leek], A. sativum [garlic] and A. schoenoprasum [chive]) which are used as food and ethnomedical purposes for centuries may cause intoxication in dogs and cats due to contents of organosulfur (disulfide, trisulfide and thiosulfonate) compounds. The material of this case was a 2 years old, 2,5 kg male Yorkshire terrier breed dog which brought to a private veterinary clinic. Anorexia, weakness, depressed and 2 times vomited was included in the history. When the diet information examined in detail, the knowledge of eating meat dish prepared with onion three days ago by dog has been reached. Hemolytic anemia determined according to the hematology results, dark urine and history supported the suspicion of onion intoxication. Symptomatic and supportive (lactated ringer's solution, metoclopramide E, C and B complex vitamins) treatment were performed. It has been observed that the blood values were close to the physiological levels in the hematological examinations that were performed at 2 and 7 days following treatment. Clinical, haematological, biochemical values returned to normal at the 15th day and patient recovered completely. The aim of this case report is point out that frequently consumed human foods like A. cepa (onion) can be poisonous to dogs and cats and should not be allowed to take place in their diets.
