Risks of Onion & Garlic for Dogs

Onions and garlic are staples in many kitchens all over the world, but did you know that they can be harmful to your pup? While these flavorful alliums may add a delicious kick to your favorite dishes, they can cause serious illness in dogs. It’s important to know the risks of onion and garlic for dogs so that you can keep your furry friend safe. Onions and garlic, whether cooked or raw, contain compounds known as thiosulfates, which can cause anemia in dogs. Anemia is a condition in which there is a decrease in the number of red blood cells, preventing adequate oxygen from reaching the body’s organs. Signs of anemia in dogs include lethargy, pale gums, rapid heart rate, and dark urine.

If left untreated, anemia can be fatal. In addition to anemia, onions and garlic can also cause digestive upset in dogs. These alliums can lead to vomiting, diarrhea, and other gastrointestinal distress in your pup. If your dog has eaten onions or garlic, watch for any changes in their behavior, such as decreased appetite, or any signs of discomfort, such as abdominal pain. It’s important to note that even small amounts of onion or garlic can be dangerous for dogs.
