Some vegetables can make dogs sick

Asparagus – NO

Dogs should not eat asparagus. While asparagus isn’t necessarily unsafe for dogs, there’s really no point in giving it to them. It’s too tough to be eaten raw, and by the time you cook it down so it’s soft enough for dogs to eat, asparagus loses the nutrients it contains. If you really want to share a veggie, something more beneficial is probably best.

Mushrooms – NO

Dogs should avoid mushrooms. Wild mushrooms can be toxic for dogs. While only 50-100 of the 50,000 mushroom species worldwide are known to be toxic, the ones that are poisonous can really hurt your dog or even lead to death. Washed white mushrooms from the supermarket could be OK, but it’s better to be safe than sorry; skip the fungi for Fido all together.

Onions – NO

Dogs should never eat onions. Onions, leeks, and chives are part of a family of plants called Allium that is poisonous to most pets, especially cats. Eating onions can cause your dog’s red blood cells to rupture, and can also cause vomiting, diarrhea, stomach pain, and nausea. Poisoning from onions is more serious in Japanese breeds of dogs like Akitas and Shiba Inus, but all dogs are very susceptible to it.

Tomatoes – NO

While the ripened fruit of the tomato plant is generally considered safe for dogs, the green parts of the plant contain a toxic substance called solanine. While a dog would need to eat a large amount of the tomato plant to make him or her sick, it’s better to skip tomatoes all together just to be safe.
