Deciding to share our home with a dog is for us the responsibility of ensuring a complete state of well-being, which includes multiple cares. Some of the most important are to provide adequate socialization, sufficient company and affection and an optimal diet.

The feeding of the dog is of great importance, as it directly interferes with your health. In fact, inappropriate nutrition acts as a trigger for multiple diseases. Many owners decide to provide their pet with homemade food as a complement to the feed. Therefore, they are informed about what foods can be toxic, but it is also necessary to know how to interpret this information.

What is the danger?

Dogs that eat large portions of onions or related vegetables (such as garlic, shallots or leeks) may have vomiting, diarrhea and abdominal pain. Worse yet, sulfur-containing molecules in these foods can destroy red blood cells, which leads to anemia. In rare cases, it can be deadly.

How serious can it be?

Only 15-30 grams of onion per kilogram of the dog’s weight is required to cause detectable changes in the blood. This is equivalent to a 13-kilogram dog eating a large onion. Sulfur compounds that cause anemia are not destroyed by cooking or drying them. So even a meat stew dish, if cooked with onions, could be harmful to your dog.

The damage can also accumulate during some meals. So even if the dog seemed fine after a night of eating leftovers containing onions. Several nights doing the same thing could be a problem. Onions and garlic are found in some pet food and treat. So it may be worth checking the labels and avoiding those products if your dog eats a lot of them.


Hence, Feeding Onion and Garlic to Dog will be dangerous. So don’t feed them with these foods. A healthy diet is necessary for dogs also. So prepare healthy food and feed your pets properly.
