Zinnias belong to a family of annuals and are considered to be one of the safest plants to have around a dog. No part of the flowering plant is considered to be toxic. Although zinnias are not poisonous to dogs, eating these colorful plants in large amounts can make a dog ill. 

As zinnias are not poisonous it is considered safe for dogs. But eating them in a large amount can cause slight illness in them. Let’s get to know about different parts of zinnias that are safe for your pup.

Zinnia leaves:

The zinnia plant can have a range of different shapes of plant, with a range of green, having both stalkless and opposite kinds.

Zinnia leaves are not poisonous to dogs and they do not produce any sap that is poisonous to dogs. Since plants are not supposed to be a part of a dog’s diet, eating too many zinnia leaves, can, nonetheless, cause problems.

One of these issues is a blockage. This is particularly true if you have a young dog at home. Puppies have weaker intestines which may get blocked easily on ingesting hard to digest leaves.

You may also want to remember that eating leave in large amounts causes blockage. If your young pet eats leaves occasionally, you can expect certain stomach issues such as constipation from your dog.

Zinnia flowers:

As colorful and vibrant as zinnia flowers are, it is normal for your puppies to take a bite of them. If they are often attracted to chew them, it might be because they like the texture of it, more than the looks.

Luckily, zinnia flowers are soft and harmless as they do not contain any toxins either. Nevertheless, it is best to be careful as flowers often carry pesticides and fertilizers on them.

Even if the flowers do not cause sickness, fertilizers may make a dog sick and lead to vomiting and diarrhea 

Zinnia seeds:

One of the easier to grow plants, zinnias are only planted once. Like all other zinnia plants, the seeds of this exciting plant are completely nontoxic and would not harm your dog even if they eat it.

When compared to other plants, zinnia seeds can cause more sicknesses like vomiting.

Are zinnias harmful to dogs? Are zinnias safe for dogs?

Sometimes a plant may have certain parts that are nontoxic to dogs but may also have poisonous parts.

Many times, the buds or stem may produce sap that can cause severe issues to a pet’s health. With zinnias, no particular part of the plant is known to produce toxins either.

While plants are not supposed to be part of a dog’s diet, you might have noticed how your dog is attempting to eat plants, flowers, and leaves all the time.

While zinnias are considered to be a safe plant to have in your house if you own one or more dogs, it might not be wise to label the plant as edible for dogs.

Generally, zinnias are edible plants for humans, and eating them would not cause any toxic reactions in your pet either. Because they are completely safe to chew for a dog, eating small amounts of the plant would not make any difference.

Sometimes if your dog has warmed in their stomach, chewing zinnia leaves can even comfort them temporarily. You should certainly refrain from adding zinnias to your plant’s diet in case you are thinking of adding fiber.

This eventually leads to constipation in dogs as the leaves are hard to digest. The same can also make your dog feel stomach churns and aches.
