A few cheese crackers will not poison a dog. Cheez-Its and similar crackers contain no onion or garlic, so the concern is salt, fat, and refined carbohydrate rather than toxicity. A stolen handful is a stomach-upset risk; a whole box is worth a call.

Why Cheese Crackers needs caution
Cheese crackers are not toxic. Reading the ingredient list of the common brands, they are wheat flour, vegetable oil, cheese, and salt, with no onion or garlic powder. The concern is a salty, fatty, calorie-dense snack that dogs are not built to eat in quantity.
Check the flavor before you relax
Plain cheddar crackers are the low-risk case. Flavored varieties are a different product: anything labelled French onion, ranch, taco, chili, or garlic can contain onion or garlic powder, and those are concentrated forms of an Allium that damages canine red blood cells. If your dog ate a flavored cracker, the flavoring, not the cracker, is what to tell your vet about.
Signs to watch for
Increased thirst, upset stomach, vomiting or loose stool; after a very large amount, lethargy or wobbliness
What to do next
Count roughly how many were eaten, leave fresh water down (never restrict it after a salty snack), and call your vet if a small dog cleared a whole box or if vomiting keeps up.

FAQ
No poison-control body lists cheese crackers as a toxin, so there is no published toxic dose. A few crackers are a non-event for most dogs. A whole box matters mainly for the sodium and fat load, and most for a small dog or one prone to pancreatitis.
Yes, for a handful. Make sure fresh water is available and watch for stomach upset over the next day.
A whole box or bag, especially for a small dog; repeated vomiting; or a dog with a history of pancreatitis, heart disease, or kidney disease, where a sodium and fat load is not trivial.
No. A single cheese cracker is not a toxic exposure for a dog of any size. There is nothing to treat and nothing to watch for beyond the usual: it is a salty crumb, not a poisoning.
Not meaningfully. The original flavors are the same picture of wheat, oil, cheese, and salt, with no onion or garlic. Treat them the same way, and check the label on any flavored version.
