Salted cracker
CautionA few saltines will not cause salt poisoning. What matters is the ingredient panel: onion and garlic powder in seasoned crackers, the sodium load in a dog with heart or kidney disease, and empty calories.

More about this food
A dog that stole a few crackers off the coffee table is rarely an emergency, and the numbers say why. Merck puts salt toxicosis signs at 2-3 g/kg of sodium chloride with an acute oral lethal dose around 4 g/kg. For a 10 lb (4.5 kg) dog that means roughly 9-13 g of salt at once. A 100 g sleeve of salted crackers carries somewhere around 500-900 mg of sodium, about 1.3-2.3 g of salt, so even the whole sleeve sits well under the acute threshold.
The real question is what kind of cracker. Onion-and-chive Triscuits, French onion flavor, garlic butter crackers, Cheez-Its, Goldfish and party Chex Mix all carry onion or garlic powder. Allium toxicity survives cooking, drying and grinding, and dried powder is far more concentrated per gram than the fresh bulb. Merck reports clinical signs in dogs from 15-30 g/kg of raw onion and notes garlic is 3-5 times more potent than onion. That changes the whole picture, because oxidative red-cell damage begins within 24 hours but hemolysis typically declares itself at 3-5 days. A dog that looks fine tonight tells you nothing; watch for pale gums, weakness, jaundice and dark urine across that window.
Second, consider the dog. A dog on furosemide for mitral valve disease, or one managing chronic kidney disease or ascites on a sodium-restricted prescription diet, does not have room in the budget for salty snacks. Third, calories. AKC describes bread as filler that adds nothing your dog's food does not already supply, and crackers sit in exactly the same category.
So pick the box back up and read it. If it lists onion, garlic or chive powder, or if it is a sugar-free cracker containing xylitol, call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 with the box in hand. If it is plain and the amount was small, leave plenty of fresh water down and watch. Never restrict water after a salty ingestion; sodium has to come down slowly to avoid cerebral edema. And never use salt or salt water to make a dog vomit. Pet Poison Helpline warns explicitly that this technique causes salt poisoning in its own right.
Frequently asked questions
- My dog ate a whole sleeve of saltines. Is that salt poisoning?
- Almost certainly not on the sodium alone, since a full sleeve stays well below the 2-3 g/kg threshold for most dogs. Expect thirst, frequent urination and possibly vomiting or loose stool, leave water down, and call your vet if the crackers were onion or garlic flavored.
- He ate garlic-and-onion crackers and seems totally normal.
- Normal tonight does not rule it out. Allium damage to red cells starts within 24 hours but hemolysis usually shows at 3-5 days as pale gums, lethargy, jaundice or dark urine. Call your veterinarian with the amount, the time and your dog's weight and ask whether a CBC is warranted.
- Are unsalted crackers an okay training treat?
- They are not harmful in tiny amounts, but they are filler calories with no nutrient your dog's food lacks. Keep all treats inside 10% of daily calories, and a piece of carrot or plain kibble does the same job with less cost to the diet.
