If your dog swipes a fry off the plate, the ketchup usually isn’t far behind. But can dogs eat ketchup?
Usually, no. A tiny lick is unlikely to be a major problem for most dogs, but ketchup is not something you want to share on purpose.
The problem is not just the tomato. Most ketchup also brings extra sugar, salt, and seasonings, and some varieties may contain garlic or onion.
If your dog ate a large amount of ketchup or any sugar-free ketchup, call your veterinarian for guidance.
Key Takeaways
