Italian red onions, also called Tropea onions, are popular in Italian cooking. They originate near the city of Tropea, Italy, where you can buy them fresh from the farmers during their harvest time in May-June. Italian red onions have a sweeter taste and are juicier than other types of onions. Some people even make jam with Tropea onions. They’re also popular in salads, sauces, roasted/grilled and more.

Can my dog eat Italian red onions? Can my puppy eat Italian red onions? No, onions—all types—are not recommended for dogs or puppies. Onions can be toxic to dogs due to two substances they contain: thiosulfate and organosulfur. All parts of the onion are toxic to dogs, including the stem, juice, leaves and flesh. All forms are toxic, too, such as dried/powdered onions. What happens if my dog ate onions? If your dog or puppy eats a small slice of onion, he’ll more than likely be OK. But if he eats even a quarter of an onion, he could become quite sick. He could develop a form of anemia called Heinz body anemia or could develop onion toxicity. If your dog eats part of an onion or other food containing a lot of onion, be sure to contact your veterinarian and get an appointment for your dog to see them right away.
