Dogs can eat sesame seeds in small amounts as they are not toxic or poisonous to them. However, sesame seeds should only be given in moderation because they contain high amounts of fat and fiber, which can cause stomach upset such as vomiting, diarrhea, or pancreatitis if consumed in large quantities. Additionally, sesame seeds are small and could pose a choking hazard. They do not provide significant health benefits to dogs compared to other treats, so they are best used sparingly and not as a regular part of the diet. Always ensure sesame seeds given to dogs are plain and unsalted, and consult a veterinarian before introducing them to a dog's diet.
