Depends on the form, the amount or the dog.
CAUTION: Plain crackers are not toxic to dogs, but they add little nutrition and are often high in salt and refined carbs, which in quantity can cause excess thirst, urination, or GI upset. Avoid seasoned varieties — onion or garlic powder, common in ranch or French onion flavors, is genuinely toxic per ASPCA. Feed plain, unsalted only, sparingly.
- Safe form
- Plain, unsalted or low-sodium crackers (e.g., plain saltines or water crackers), given occasionally as a small treat, broken into small pieces, with no butter, cheese spread, or seasoning.
- Unsafe form or part
- Crackers seasoned with onion or garlic powder (ranch, French onion, pizza, "everything" blends), heavily salted or buttered/cheese crackers fed in quantity, and any cracker product sweetened with xylitol/sugar alcohols (some sugar-free or "keto" crackers).
- Preparation
- Only plain, unsalted varieties; no butter, dips, or cheese; break into small pieces to reduce choking risk; always check the ingredient label for onion powder, garlic powder, or xylitol/sugar alcohols before sharing, and treat any seasoned or "flavored" cracker as off-limits.
- Do not offer
- Crackers seasoned with onion or garlic powder (ranch, French onion, pizza, "everything" blends), heavily salted or buttered/cheese crackers fed in quantity, and any cracker product sweetened with xylitol/sugar alcohols (some sugar-free or "keto" crackers).
- Deliberate feeding
- Only once the form and amount are clear
- Hazard level
- 1 of 4
If your dog has already eaten crackers
A few plain crackers usually just warrants watching for stomach upset. If a dog eats a large quantity of salty crackers, monitor for excessive thirst/urination, vomiting, diarrhea, tremors, or seizures and call a vet if these appear. If the crackers were onion/garlic-seasoned or contained xylitol (check the ingredient label), contact a veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) right away rather than waiting for symptoms to develop.

Which form of crackers the sources actually cleared
Plain, unsalted or low-sodium crackers (e.g., plain saltines or water crackers), given occasionally as a small treat, broken into small pieces, with no butter, cheese spread, or seasoning.
Preparing crackers for a dog
Only plain, unsalted varieties; no butter, dips, or cheese; break into small pieces to reduce choking risk; always check the ingredient label for onion powder, garlic powder, or xylitol/sugar alcohols before sharing, and treat any seasoned or "flavored" cracker as off-limits.
What actually goes wrong
- Crackers are a "salty snack food" — ASPCA warns excessive salt intake can cause increased thirst/urination and, with larger amounts, electrolyte abnormalities, vomiting, diarrhea, tremors or seizures. Refined flour/oil crackers add empty calories and can trigger GI upset or contribute to weight gain/pancreatitis risk if fatty (e.g., butter or cheese crackers). The bigger hazard is seasoning: flavored crackers (ranch, French onion, pizza, "everything," some cheese blends) frequently contain onion or garlic powder, which ASPCA identifies as damaging red blood cells and causing anemia in dogs. Some low-carb/"keto" crackers use sugar alcohols — check the label for xylitol, which is a veterinary emergency, not addressed on this specific page but relevant to compound snack products generally.

How much counts as too much
All treats combined should generally stay within 10% of daily calories for a healthy adult dog in ideal body condition; individual needs vary.
The table below is the WSAVA reference allowance, printed as published. It is not a portion of crackers: it is the total treat-calorie ceiling that everything given outside meals has to fit inside. Average healthy adult dog in ideal body condition. A veterinary team should set the individual dog's daily energy requirement.

Downloaded the raw HTML of the cited ASPCA page directly (not via a paraphrasing fetch) and grep-verified both quotes appear verbatim.
