For a dog parent, their beloved pooches are a source of joy and contentment. Thus, they leave no stone unturned to ensure their pets receive nutritious food and plenty of exercise. In addition to providing them with nutrient-rich foods, dog parents should also know about the hidden dangers of certain seemingly innocuous foods that dogs may ingest when they can access them. Here are 11 human foods that can be toxic to dogs: Grapes and raisins Grapes and raisins can be highly toxic to dogs, although the exact cause of their toxicity is unknown. Ingesting grapes or raisins, even in small quantities, can cause kidney failure and even death among dogs. Therefore, it is important to keep grapes and raisins out of a dog’s reach. Mushrooms Although only a few types of mushrooms are poisonous to dogs, the poisonous ones can prove lethal. Moreover, it is difficult to distinguish the harmful mushrooms from the safe ones. Hence, to err on the side of caution, it is advisable to avoid feeding mushrooms to dogs. Xylitol This artificial sweetener is increasingly used as a sugar substitute and is harmless to humans. However, even small quantities of xylitol are dangerous for dogs. In humans, this sweetener does not cause the pancreas to release insulin.
