NYC Spring Flowers & Dog Safety
What Every Dog Parent Should Know Before Chasing Tulips

Let's talk about something important that every dog parent should know: spring flowers are stunning, but some of them are also toxic to your dog. This doesn't mean you can't enjoy the season with your pup — it just means going in informed, and ensure they definitely don't consume these. Here's what you need to know.
Tulips & Daffodils: Beautiful, But Dangerous
Tulips contain allergenic lactones concentrated primarily in the bulb, though the stems, leaves, and flowers also carry toxins. Ingestion can cause drooling, nausea, vomiting, diarrhea, and in larger amounts, increased heart rate and difficulty breathing.
Daffodils (narcissus) contain lycorine, an alkaloid that triggers intense vomiting. The bulb is the most toxic part, but all parts of the plant — stem, flower, and leaves — are considered poisonous. Symptoms include vomiting, diarrhea, abdominal pain, and in severe cases, cardiac arrhythmia and tremors.
Both flowers are planted widely across New York City's public parks every spring — which is exactly why we felt it was important to say something. When you're walking through Bryant Park or strolling the Park Avenue malls, keep your dog close, on leash, and away from the beds. A sniff from a distance is fine. Chewing on a stem is not.
If you suspect your dog has ingested any part of a tulip or daffodil, contact your vet or the ASPCA Animal Poison Control Center immediately: (888) 426-4435.
