It's well known that chocolate is toxic to dogs, but not everyone is aware of xylitol. In an ongoing survey by Preventative Vet, over 50 percent of respondents weren't aware of xylitol or the danger it poses to dogs. In many cases, this sweetener can be even more toxic than chocolate (the picture above shows a dangerous amount of dark chocolate compared to the number of xylitol-containing sugar free gum pieces that could be deadly).
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. Even small amounts can cause life-threatening hypoglycemia and liver failure. Fortunately dogs can recover if treated promptly.
Last year I wrote that xylitol was becoming more common in household products since it can reduce calorie intake. I always knew to be careful with sugar free gum, but the sweetener has been popping up in cookies, cough drops, toothpaste, cosmetics, and mouthwash.
To make things worse, I recently learned that xylitol is being included in some specialty brands of peanut butter. This is alarming because many people use peanut butter to fill Kongs or to make dog treats. Currently no major brand is affected, but this highlights the need to be vigilant in checking the ingredients on the products we use. It's important to note that xylitol can be listed on labels as sugar alcohols, which encompasses many different sugar alcohols, including xylitol.
Please spread the word so that we can make sure no dog is accidentally affected by xylitol poisoning!
