Butter isn't acutely toxic, but it's essentially pure fat, and even small regular amounts can contribute to weight gain and pancreatitis risk over time.
There's no specific toxin in butter — the concern is purely its fat density. A dog stealing a small amount off a counter is unlikely to have a serious reaction, but butter offers no nutritional benefit worth the fat load, and repeated exposure is a real risk factor for pancreatitis in predisposed dogs.
