Types of peanuts: safe vs. unsafe
| Type | Safe? | Notes |

Peanut butter: watch out for xylitol
Peanut butter can be a great treat, but always check the label. Some brands contain xylitol (also called birch sugar or sugar alcohol), an artificial sweetener that is extremely toxic to dogs.
Safe peanut butter should contain:
- Just peanuts (and possibly oil and a small amount of salt)
- No xylitol
- No added sugar
- No chocolate
Symptoms of xylitol poisoning
If the peanut butter contains xylitol, symptoms can appear within 15 to 30 minutes:
- Sudden drop in blood sugar (hypoglycemia)
- Vomiting
- Weakness and disorientation
- Seizures
- Liver failure (in severe cases)
If you suspect xylitol ingestion, seek emergency veterinary care immediately.
