Spring brings sunshine, blooms—and hidden dangers for pets. Learn how to keep your dogs and cats safe from toxic plants, garden chemicals, lilies, and chocolate with tips from Landrum Veterinary Hospital.
Spring Is in the Air — and So Are Hidden Pet Hazards
Spring is almost in the air! With the change in weather, plants wake from their winter slumber — and pets like Betty and Milly are eager to explore the garden, tasting every new bloom they find. Unfortunately, toxic plants and lawn chemicals can make pets sick, sometimes causing mild symptoms like vomiting and diarrhea, but in severe cases leading to kidney or liver failure, neurological problems, or even death.
Below are a few important tips to help you prepare for potential toxic situations your dogs or cats may encounter this season.
1. Call Your Veterinarian Right Away
If you suspect your pet has eaten something poisonous, call your veterinarian immediately. Your vet can advise you on whether to monitor your pet at home, come in for treatment, or perform first-aid steps before arriving at the clinic. Quick action can make all the difference.
2. Keep Hydrogen Peroxide on Hand (and Use Only Under Guidance)
Always keep an in-date bottle of hydrogen peroxide in your medicine cabinet. In some cases, your veterinarian may recommend inducing vomiting soon after ingestion (usually within one to three hours).
However, never induce vomiting without guidance — some substances, like corrosive chemicals, can cause more harm when vomited back up. Our veterinarians will instruct you on whether it’s safe and how much to give.
3. Use Trusted Resources for Toxin Information
The ASPCA Poison Control website offers an excellent resource for identifying potential toxins, including plants and household chemicals.
ASPCA Poison Control Center
Toxic and Non-Toxic Plant List
If your pet ingests something harmful, you can also call the ASPCA Poison Control Hotline at (888) 426-4435 (note: a consultation fee applies). They can provide detailed treatment advice and work directly with your veterinarian if needed.
4. Train and Plan for a Safer Garden
Try to train your pet not to chew on plants or use barriers to keep them out of garden areas. Deterrent sprays like Yuck! or Bitter Apple can help discourage curious nibbling. When planting, choose pet-friendly plants such as marigolds, rosemary, catnip, and zinnias — safe options that add color and fragrance without posing risks.
If your pet does ingest fertilizer or lawn chemicals, keep the product packaging for your veterinarian to review. The label often lists active ingredients and emergency contact numbers that can speed up treatment.
5. Beware of Indoor Spring Dangers: Lilies and Chocolate
Springtime also brings hazards inside the home in the form of flowers and sweet treats.
Lilies — Beautiful but Deadly to Cats
True lilies (Tiger, Day, Asiatic, Easter, Stargazer) are extremely toxic to cats, even in small amounts. Ingesting or even contacting pollen or water from a vase can cause acute kidney failure within days. Symptoms may include lethargy, vomiting, increased thirst, and changes in urination.
If you think your cat has come into contact with lilies, call or visit your veterinarian immediately. Other “non-true” lilies like Lily of the Valley, Peace, and Calla lilies can also cause gastrointestinal or heart issues and should be avoided.
Chocolate — A Sweet Treat, but Not for Pets
Dogs and cats cannot safely metabolize methylxanthines (theobromine and caffeine) found in chocolate. Dark and baking chocolates are the most toxic, while milk chocolate is less so but still dangerous. Chocolate toxicity can cause hyperactivity, tremors, heart irregularities, vomiting, diarrhea, and even death.
Sugar-free candies containing xylitol are also highly toxic and can cause a dangerous drop in blood sugar, leading to seizures or coma.
