A large dose of fat can inflame the pancreas, and the fat cap off a brisket is close to a worst case: dense rendered fat, heavy salt, and a rub that is usually mostly garlic and onion powder. Pancreatitis can be severe and often shows up 12 to 48 hours later. The details below use the specific facts for this exposure, rather than treating it like every other food question.
1. Start with the exact exposure
For a closely related comparison, read Brisket. There is no clean threshold. A single fatty meal is enough to trigger pancreatitis in a susceptible dog, and small breeds and dogs with prior episodes are at higher risk. The rub adds a separate garlic and onion exposure that is dose-by-weight.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Burnt Ends. A trimmed sliver in a large dog is usually watched. A real portion of fat cap is not something to wait out. If your dog ate more than a bite, if it was heavily rubbed, if your dog is small or has had pancreatitis, or at the first sign of a hunched back and refusal to eat.
3. If the details are uncertain
Follow the first 10 minutes guide. Withhold food, keep water available, and call your vet. Pancreatitis is easier to manage early, so do not wait for symptoms if the amount was large.
