Autumn Crocus
The autumn crocus is hazardous for pets as it can cause a burning sensation in the mouth, along with vomiting, diarrhea, and seizures when ingested by both dogs and cats. It can also cause liver and kidney damage and even shock. While the entire plant is toxic, it’s the bulbs that have the highest toxicity so Hyder recommends adding temporary fencing or low garden borders to block off access to newly planted bulbs.

Begonia
Begonias are a popular flower for pots and hanging baskets, but the plant can also cause kidney failure in cats and dogs. The most toxic part of the plant is underground, so if you do choose to have begonias in your yard, keep them out of reach from pets, especially those that like to dig.

Daffodil
A staple for making a big splash in many yards every spring, daffodils are considered poisons to dogs, although it is the plant’s bulb that is the most toxic. When dogs ingest any part of the plant, it can cause diarrhea and vomiting, along with abdominal pain, convulsions, and a drop in blood pressure.

Tulip
Another bulb plant that is toxic to dogs is the tulip which can cause nausea and excessive drooling and mouth irritation when ingested. Similar to daffodils and autumn crocus, this plant’s bulb is the most toxic so it’s a good idea to take extra precautions just after planting to keep pets away.

FAQ
What should I do if my pet eats a potentially poisonous plant or flower?
“If you see or suspect that your pet has eaten part of a toxic plant or flower, don’t wait for symptoms to appear,” Hyder says. “Quick action can make a huge difference in how your pet responds to treatment.” These are the steps to take ASAP:
- Remove any remaining plant material from your pet’s mouth, if safe to do so.
- Identify the plant as best you can. Take a photo or bring a piece with you inside.
- Call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.
- Do not induce vomiting unless directed to do so by a veterinary professional.
The bottom line: When it comes to plant poisoning, earlier treatment usually means better outcomes, Hyder says.
What signs should I look for if my pet may have eaten a toxic flower?
Symptoms depend on the type of plant and how much your pet ingested, Hyder says, but common warning signs your pet may have eaten a toxic plant include:
- Vomiting or diarrhea.
- Drooling or foaming at the mouth.
- Lethargy or weakness.
- Loss of appetite.
- Trembling or seizures.
- Changes in heart rate or breathing.
- Pale gums.
“In cats, even brushing up against certain plants like lilies and then grooming themselves can cause serious toxicity,” Hyder adds. “If you notice any of these signs, or even if you’re just unsure, it’s best to call your veterinarian right away.”
