2. Onions, Chives, Leeks and Garlic
Onions, chives, leeks, and garlic are part of the Allium plant family, and they all are toxic to dogs. Of all the plants, garlic is the most toxic to dogs. When ingested, dogs can experience weakness, gastrointestinal issues, pale gums and an increase in heart rate. Eating foods from the Allium plant family can also cause damage to red blood cells in dogs. It should be noted that the effects of toxicity from these foods may not be readily apparent in dogs, and dog owners are encouraged to monitor their dogs for possible symptoms of poisoning if any of these foods are consumed.
