Why is Sorbitol a Problem for Pets?
Sorbitol is a sugar alcohol used as a sweetener and laxative in many sugar-free foods, gums, candies, baked goods, and some medications.
Pets lack the enzymes to properly digest sugar alcohols. When ingested, sorbitol draws water into the intestines via osmosis, leading to severe diarrhea, gas, and abdominal bloating.
While not as acutely toxic as xylitol, large amounts can cause significant fluid loss, electrolyte imbalances, and discomfort. The diarrhea can be explosive and lead to dehydration, especially in small pets.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of artificial-sweetener-sorbitol poisoning
