Some tricks and treats can be hazardous to pets: Keep your pets safe this Halloween season Skip to main content Some tricks and treats can be hazardous to pets: Keep your pets safe this Halloween season October 05, 2026 Halloween may mean chocolate, candy, and costumes for people, but some of the things that make the holiday fun can pose health and safety risks for pets.
LSU Vet Med encourages pet owners to take a few precautions to keep dogs and cats safe during Halloween celebrations.
TREATS Why is chocolate dangerous for dogs?
Chocolate contains theobromine and caffeine, naturally occurring chemicals known as methylxanthines.
People can process these substances relatively quickly, but dogs metabolize them much more slowly.
As a result, the chemicals can build up in a dog's body and cause potentially serious illness.
Pet owners should know: Not all chocolate poses the same risk.
The darker and more bitter the chocolate, the higher its concentration of theobromine and caffeine.
Cocoa powder, baking chocolate and dark chocolate generally pose a greater risk than milk chocolate.
White chocolate contains very little theobromine but can still cause gastrointestinal problems because of its high fat and sugar content.
The danger depends on both the amount eaten and the dog's size.
The report adds to ongoing university-led research relevant to veterinary medicine, animal health, and clinical decision-making.
