Morning glory vines cause mild stomach upset, but the seeds are the real concern: they contain lysergic (LSA) alkaloids that affect the nervous system, and a large amount of seeds can cause hallucinations and agitation in dogs. The seeds, not the flowers, are what make this plant worth caution.

Why Morning Glory is dangerous
Morning glory seeds contain indole (lysergic acid) alkaloids that act on the nervous system. The vine and leaves cause mild gastrointestinal upset, but eating a quantity of seeds can bring on neurologic signs, including disorientation and hallucination-like behavior.
Signs to watch for
Vomiting, diarrhea; with seeds, agitation, disorientation, wobbliness, tremors, a racing heart
What to do next
Keep dogs away from seed heads and stored seed packets, and call your vet or poison control if seeds were eaten or your dog seems disoriented or agitated.
A nibble of leaf or flower usually causes mild stomach upset. The concern is the seeds: a small amount is a low risk, but a larger quantity of seeds carries a real neurologic effect, and small dogs reach that point sooner.
Can I treat this at home?
A small nibble of vine or flower in a bright dog can usually be watched at home. Seed ingestion is not a wait-and-see situation.
When should I call the vet?
Any real amount of seeds, a small dog, or signs of agitation, disorientation, wobbliness, tremors, or a racing heart.
