Why it’s harmful to dogs
Tulips are spring bulbs grown in garden beds, pots and cut-flower bouquets. They look harmless, but the whole plant contains toxins, and the ASPCA notes the highest concentration is in the bulb. Merck Veterinary Manual lists tulips among the ten plants behind the most calls to Pet Poison Helpline.
The ASPCA names tulipalins A and B as the toxic principles. Pet Poison Helpline says a small nibble of leaf, stem or flower may bring mild nausea and vomiting, while eating bulb material risks persistent stomach upset and lethargy. Signs are mostly digestive: drooling, vomiting, diarrhea and loss of appetite.
The real risk comes from bulbs. Dogs dig up freshly planted bulbs in fall, and bulbs stored in a garage or bag can be easy to steal. So the amount, and whether any bulb was eaten, is the first thing your vet will ask.
If your dog ate tulips
Take away what's left and check your dog's mouth for plant pieces. A bite of petal or leaf often leads to mild drooling or vomiting, but call your vet or a poison helpline if your dog ate any bulb, a large amount, or you're unsure how much. In the US, you can reach ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (fees may apply); elsewhere, call your local emergency vet. Please don't try to make your dog vomit at home.
Watch for repeated vomiting, diarrhea, drooling that doesn't stop, or unusual tiredness. Offer small sips of water and call your vet if signs last or worsen.
Mention any fertilizer, bulb treatment or pesticide used in the bed.
Keeping your dog safe
Plant bulbs where your dog can't dig, or cover new beds with mesh or fencing until the soil settles. Keep unplanted bulbs in a closed container on a high shelf. Put cut tulips in a vase out of reach and sweep up dropped petals.
Give diggers something better to excavate, like a sandbox of their own, and teach "leave it". For spring color that is listed by the ASPCA as non-toxic to dogs, camellias and petunias are options.
