A plain graham cracker will not poison a dog. No poison-control body lists them as a toxin; they are a sugar and refined-carb snack with modest salt. The exceptions ride along with them: chocolate-dipped grahams and s'mores put real chocolate in reach.

Why Graham Crackers needs caution
Graham crackers are not toxic. Reading the label of the common brands, they are flour, sugar, oil, honey or molasses, and a little salt, with no onion, garlic, or other listed toxin. The concern is empty calories and sugar a dog does not need, and the cinnamon variety carries only a dusting, far below the quantity where cinnamon itself irritates.
S'mores are a chocolate event, not a cracker event
A dog that raids the campfire tray has eaten graham cracker, marshmallow, and chocolate, and only the chocolate counts as a poisoning risk. Dark and baking chocolate matter at far smaller amounts than milk chocolate. Estimate the chocolate type and amount, use our chocolate page, and let the cracker and marshmallow go; also check sugar-free marshmallows for xylitol before shrugging them off.
Signs to watch for
Usually none; after a large amount, stomach upset, gas, or loose stool

What to do next

A closer look at graham crackers
Graham crackers are not toxic. Reading the label of the common brands, they are flour, sugar, oil, honey or molasses, and a little salt, with no onion, garlic, or other listed toxin. The concern is empty calories and sugar a dog does not need, and the cinnamon variety carries only a dusting, far below the quantity where cinnamon itself irritates. 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 Goat Milk. No poison-control source publishes a toxic dose, because there is not one. A cracker or two is a non-event for any size dog. A whole box matters the way any sugar-and-carb binge matters: stomach upset now, and a weight problem if it becomes routine.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Greek Yogurt. Yes. A stolen cracker or a handful needs nothing beyond watching for a day of possible stomach upset. Only if the crackers were chocolate-dipped or part of s'mores, if a sugar-free variety listed xylitol, or if vomiting or diarrhea keeps up beyond a day.
3. If the details are uncertain
Follow the first 10 minutes guide. Check what kind of cracker it actually was. Plain or honey graham needs no action; chocolate-coated changes the question to chocolate, and that page's math applies.

They work in a pinch but they are a sugar delivery system, and the calories add up fast against a dog's daily needs. A purpose-made training treat or plain vegetable pieces do the same job with less sugar.
