Top Harmful Spring Plants for Dogs
Here are some of the most common—and often overlooked—plants to be cautious of during springtime:
1. Daffodils
Toxic parts: Bulb (most toxic), leaves, and flowers
Why they’re dangerous: Daffodils can cause vomiting, diarrhoea, abdominal pain, and even heart or breathing issues in serious cases.
2. Tulips
Toxic parts: Bulbs primarily, but all parts can cause irritation
What to look for: Drooling, vomiting, and lack of appetite. In severe cases, dogs may appear unsteady or show signs of depression.
3. Bluebells (UK Native)
Toxic parts: Entire plant
Risk: Ingestion can lead to nausea, vomiting, diarrhoea, and heart issues in larger quantities. These beautiful woodland favourites are often scattered across walking paths.
4. Crocuses
Two types:Spring crocus (milder)—may cause an upset stomach
Autumn crocus (much more toxic)—can lead to organ damage
Tip: Always treat unknown crocus species with caution.
5. Lily of the Valley
Toxic parts: Entire plant
Effects: This sweet-looking flower can cause vomiting, heart arrhythmias, and seizures. Just a small amount can be dangerous.
6. Azaleas & Rhododendrons
Where they grow: Gardens and park borders
Danger: Even a few leaves can cause drooling, vomiting, diarrhoea, and in some cases, coma or death.
Symptoms of Plant Poisoning in Dogs
If your dog has eaten something unknown, watch for:
Vomiting or diarrhoea
Drooling or foaming at the mouth
Lethargy or collapse
Difficulty breathing
Tremors or seizures
When in doubt, contact your vet immediately. If possible, bring a photo or sample of the plant your dog may have eaten.
How to Keep Your Dog Safe This Spring
Know what’s growing in your garden: Remove or fence off toxic plants
Stay alert on walks: Especially in wooded areas and landscaped parks
Discourage random snacking: Train a solid “leave it” or use a long line to guide their exploring
Supervise curious puppies: Young dogs are more likely to chew unfamiliar plants
