General Tips:
* Always check the ingredients of human food before feeding it to your dog.
* Avoid giving dogs any table scraps that contain ingredients that are toxic to them.

Note: The severity of the symptoms and the amount of food needed to cause harm can vary depending on the dog's size and breed.
It is always best to err on the side of caution and avoid giving your dog any food that is not specifically meant for them. If you have any questions about what foods are safe for your dog, consult with your veterinarian.
