Poisonous to: Cats, Dogs
Level of toxicity: Generally mild to moderate
Common signs to watch for:
- Increased heart rate
- Increased respiratory rate
- Difficulty breathing
Both hyacinths and tulips belong to the Liliaceae family, and contain allergenic lactones or similar alkaloids. The toxic principle of these plants is very concentrated in the bulbs (versus the leaf or flower), and when ingested in large amounts, can result in severe clinical signs. Severe poisoning from hyacinth or tulip poisoning is often seen when dogs dig up freshly planted bulbs or having access to a large bag of them. When the plant parts or bulbs are chewed or ingested, it can result in tissue irritation to the mouth and esophagus. Typical signs include profuse drooling, vomiting, or even diarrhea, depending on the amount consumed. With large ingestions, more severe symptoms such as an increase in heart rate, changes in respiration, and difficulty breathing may be seen.
If you suspect your dog has ingested hyacinths or tulips (particularly the bulbs), contact your veterinarian or Pet Poison Helpline for treatment recommendations.
