Read the full first-aid guide: what to do if your pet ate something toxic
UC's Statewide Integrated Pest Management Program builds its home-and-landscape guidance specifically for California conditions - the program states outright that its "management suggestions are specific to pests and conditions in California" and that its audience includes "urban Californians" alongside UC Master Gardeners and nursery staff. Within that guidance, gladiolus gets its own page: a corm-grown perennial "often planted in borders, planting beds, or pots" for its tall, colorful spikes, needing full sun, regular water, and - because the flower stalks can get top-heavy - staking to stay upright. The same page runs through a long list of California pests and diseases that target it, from thrips and aphids to fusarium wilt, which is part of why the corms a home gardener plants each spring in a California border bed need active upkeep, not just a spot in the ground.
ASPCA lists gladiolus as toxic to dogs and cats, with an unknown toxic principle and documented signs of salivation, vomiting, drooling, lethargy, and diarrhea - and specifically flags the corms (bulbs) as carrying the highest concentration, the exact plant part a gardener handles most when planting or dividing. A dog that has dug up and chewed on gladiolus corms should be watched closely for these signs; call ASPCA Animal Poison Control (888-426-4435) or Pet Poison Helpline (855-764-7661) if they appear.
