It stacks three problems into one bite: butter and cheese fat that can inflame the pancreas, lactose most adult dogs do not digest well, and a lot of salt. Versions made with garlic butter or garlic bread add an allium risk on top. 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 Cream Cheese. A small corner is unlikely to hurt a medium or large dog. A whole sandwich in a small dog is enough fat to matter. Garlic-buttered versions are a different problem and are dose-dependent by weight.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Cheese Curds. A bite of a plain grilled cheese usually just needs water, a skipped meal, and observation. If it was made with garlic butter, if a small dog ate a full sandwich, or if vomiting, a hunched back, or refusal to eat shows up.
3. If the details are uncertain
Follow the first 10 minutes guide. Note whether garlic butter or seasoned bread was used, then withhold the next meal and watch for GI signs over 24 hours.
