Should dogs eat croissants at tea time?
NO. But they can eat plain white or whole grain bread in moderation, as an occasional treat.
Before feeding your dog bread, make sure it doesn’t contain any extra ingredients, such as raisins, which could be potentially harmful.
Additionally, keep in mind that bread, along with other foods, adds extra calories to your dog’s diet and may cause weight gain if he eats too much.
