What are the Symptoms of xylitol poisoning?

As xylitol (tree sugar) ingestion may induce hypoglycemia in dogs (low blood sugar), the symptoms for hypoglycemia are the ones you'll look for, such as lack of coordination, seizures, vomiting, sudden drop in energy collapse, etc.

Xylitol can do liver damage to dogs as well, and it doesn't appear to be related to the dose. Because of this you should immediately take the dog to a veterinarian if you think he's had any xylitol. The most common source of xylitol for a dog is sugar-free gum, but there are other sugar-free human foods that have xylitol in them.
