Sunflowers are not toxic to dogs. According to multiple sources including the ASPCA, sunflowers are safe for dogs to nibble on, including petals and leaves, without causing serious harm. However, eating large quantities of sunflower plant material may cause mild gastrointestinal upset, such as vomiting or diarrhea, and the tough stems and leaves can pose a choking hazard, particularly for small dogs.
Sunflower seeds themselves are safe for dogs when given in moderation, but only if they are plain, unsalted, and shelled. The shells are hard to digest and can cause intestinal blockages or choking risks. Excessive consumption of sunflower seeds, especially with shells or salted/seasoned varieties, may also lead to digestive issues, weight gain, or pancreatitis.
In summary, sunflowers and their seeds are generally safe for dogs in reasonable amounts and with the proper preparation of seeds (shelled and unsalted), but care should be taken to avoid choking hazards or digestive upset.
