The right flowers can brighten up your home or garden space and bring a little extra color and cheer into your daily life. But you don’t want to plant anything that could present a potential hazard to your dog, especially if you have a pup who loves to chew on everything.

So where do sunflowers fall on the poison scale for dogs? Fortunately, sunflowers are not toxic to canines, and it’s relatively safe for your dog to eat any part of the plant. But there are still things you should be aware of before letting your dog run rampant in the garden.

5 Plants That Are Toxic to Your Dog

Thriving plants are spring’s whole thing—but these offenders can be perilous to pets.

Why are sunflowers safe for dogs?

Sunflowers don’t present any health risks to dogs because they are not toxic. However, this doesn’t mean your dog should eat as many of the plants as they want. Eating too much of anything, especially vegetation, can result in an upset stomach for your pup, according to Dr. Holly Anne Hills. And while sunflower seeds may have some health benefits, they present the risk of causing an intestinal blockage in your dog’s stomach.

What should I do if my dog has eaten sunflowers?

If your dog has chomped on a sunflower or two, don’t stress. They will likely pass the plant without any problems. Just make sure your dog doesn’t turn your garden into a buffet to avoid stomach upset.

You should also be wary of letting your dog consume sunflower seeds. Dogs aren’t able to break the shells the way we can, and eating sunflower seeds could cause an intestinal blockage, especially in smaller dogs.

While sunflowers may be non-poisonous, if you suspect your dog has eaten something toxic, call your vet immediately or contact ASPCA Animal Poison Control at 888-426-4435.

Diagnosing plant poisoning in dogs

If your dog has eaten a toxic plant, get them to the vet or an emergency vet clinic immediately. Bring a sample of the plant your dog consumed if possible and tell the vet how much your dog ate. The veterinarian will perform a variety of tests to determine if your dog is in any danger and will present options for next steps.

Symptoms of plant poisoning in dogs

If you notice any of these symptoms in your dog, contact the vet right away:

Vomiting or diarrhea
Loss of appetite
Difficulty breathing
Tremors or uncoordinated movements
Lethargy
Excessive drooling
Any changes in behavior

Treatment

The vet will decide on the appropriate treatment for your dog. This may include hydrogen peroxide or a similar mixture to induce vomiting or a liquid suspension of activated charcoal, which can help absorb some toxins. In more serious cases, your dog may need intravenous fluids and medications.
