Dogs should not be given white chocolate intentionally. While white chocolate contains very little to no theobromine—the toxic substance found in milk and dark chocolate that harms dogs—white chocolate is high in sugar and fat, which can negatively affect a dog's health. Consumption of large amounts of white chocolate can cause digestive upset and may lead to pancreatitis, a painful and potentially serious condition. Small accidental ingestion of white chocolate is unlikely to cause severe toxicity, but pet owners should monitor their dogs for symptoms such as stomach upset or panting and consult a vet if larger quantities are consumed or if the white chocolate contains ingredients like xylitol or alcohol that are highly toxic to dogs.
