When a dog accidentally eats garlic, it is best to go to the pet hospital for treatment in time. The amount of garlic consumed by dogs, based on their body weight, may cause anemia as long as it exceeds 5 grams per kilogram. Therefore, if the amount of garlic is relatively small and the dog swallows less, you can choose to feed the dog some gastrointestinal anti-inflammatory drugs. Of course, it is best to choose milder ones, because garlic also has certain harmful effects on the gastrointestinal tract, and it is not just garlic. It is best not to feed green onions, fennel, onions, etc. to dogs.
