It's widely known that xylitol, an ingredient in sugar-free gum, is toxic to dogs. Even small amounts can cause life-threatening hypoglycemia and liver failure. This has led me to be really careful about leaving packs of gum in handbags I leave around the house. I also keep gum packs (and chocolate) in a secure plastic bin in my pantry, just to be sure no hungry dogs get into the dangerous treats.
But I recently discovered that many more household products contain xylitol. In addition to other edible goods, like cookies, cough drops, and medications, the ingredient has been popping up in toothpaste, cosmetics, and mouthwash. The Pet Poison Hotline even found a line of clothing with xylitol embedded in it!
Clearly it's important to check the ingredients of the products you have lying around the house and keep them away from your pets. Xylitol is typically listed in the “Other ingredients” or “Inactive ingredients” section, but it's also been seen in the “Supplement Facts” box, so make sure you read the package closely. Sometimes the ingredients won't be listed as xylitol, but may be included as “sugar alcohols,” which encompasses many different sugar alcohols, like xylitol.
If your pet has ingested a product with xylitol in it, immediately call a veterinarian. The ingredient is so toxic that symptoms can show up within 10 minutes of ingestion. This includes weakness, lethargy, loss of coordination, seizures, vomiting, and rapid breathing. Fortunately dogs can recover if treated promptly.
This just shows how important it is to know what's in the products in your home.
