Butter is nearly pure milk fat, and the classic exposure is not a lick: it's the whole stick off the counter, sometimes wrapper included. One is a non-event; the other is a genuine fat bomb with a side of foil.

Why Butter needs caution
At around 80 percent fat, butter is one of the densest fat loads in the kitchen, and a large fatty meal is a recognized trigger for pancreatitis in susceptible dogs. Lactose is nearly absent, so this is a fat problem, not a dairy-digestion one. Compound butters change the math: garlic and herb versions bring Alliums, which damage red blood cells.
The stick-and-wrapper case
A whole stick usually causes greasy diarrhea and not much else in a healthy large dog, but it's a real pancreatitis risk in small or prone dogs. Swallowed foil or paper wrappers usually pass; watch for vomiting or straining. Note whether it was one stick or the whole box, because vets ask.
Count the sticks and check the label for garlic. Withhold other rich food, expect unimpressive stools, and call your vet if your dog is small, pancreatitis-prone, or the butter was a compound one.
