As proud Michiganders, we’ve learned to smile at “false spring” rather than fear it. Sure, a surprise cold snap may still sneak in, but the longer days, brighter sunshine, and first pops of green across Michigan are clear signs that a new season is unfolding. There also comes a shift in potential household and outdoor hazards. Spring introduces new plants, lawn treatments, and environmental factors that can pose unexpected risks to curious noses and paws. A little planning and awareness now can help prevent accidental exposures and keep your pets safe as we head into the warmer months.
Below are a few common spring hazards to keep in mind:
Plants & Flowers
Many popular spring flowers can pose a health risk to your pets. To help make plant choices easier, we’ve included a reference list below highlighting common toxic and non-toxic plants. Use it as a guide when planning your garden or selecting flowers for your home so you can enjoy the season safely alongside your furry companions.

Lawn Treatments & Chemicals
Spring lawn care often involves fertilizers, herbicides, and pesticides, all of which can pose risks to pets if proper precautions aren’t taken.
If you treat your lawn:
- Keep pets off treated areas until sprays are completely dry and granular products are watered in and dry. This typically takes 24–72 hours, depending on weather conditions.
- Store all lawn products securely and inaccessible to pets. Clean up spills promptly, following the manufacturer guidelines.
- Never mix household cleaners, as certain combinations can create harmful fumes for both pets and people.
To reduce exposure:
- Schedule treatments during times your pet will be away from home.
- Treat sections of your yard one at a time to allow safe outdoor access.
- If using a professional lawn service, ask for a list of products they apply and keep that information on hand.
If accidental exposure occurs:
- Gently wash your pet’s paws and belly with warm water and mild soap.
- Do not induce vomiting unless directed by a veterinary professional.
- Contact a pet poison resource immediately and have the product name available.
Quick action and accurate information makes all the difference in these situations.
Mold: A Hidden Outdoor Hazard
An often-overlooked spring toxin involves mold growth on nuts, particularly walnuts. A mold called Aspergillus flavus can grow on improperly stored or moisture-exposed nuts and produces aflatoxin, a dangerous substance.
According to the American Kennel Club, ingestion of aflatoxin in dogs can lead to:
- Decreased appetite
- Vomiting
- Liver damage
- In severe cases, death
Additionally, moldy walnuts may contain another toxin (penitrem A) that can cause tremors, seizures, and vomiting.
Even if you don’t have walnut trees on your property, squirrels often bury nuts in nearby yards, meaning your pet could encounter them unexpectedly. Monitor pets outdoors and discourage them from eating anything found on the ground.
