Can Dogs Eat Peanut Butter?
Why it’s a sometimes-food
Plain peanut butter is a good source of protein and healthy fats, and most dogs love it. The danger is xylitol, a sugar substitute used in some "no sugar added" brands — even a small amount of xylitol causes rapid hypoglycemia and liver failure in dogs.
How to serve it safely
Check the label: the only ingredients should be peanuts (and maybe salt). Give no more than a teaspoon for a medium dog, ideally smeared in a lick mat or puzzle toy.
Warning signs to watch for
If xylitol was eaten: vomiting, weakness, wobbliness, collapse or seizures within 30 to 60 minutes. High fat in general can also trigger pancreatitis in sensitive dogs.
When to call the vet
If a product containing xylitol was eaten, go to a vet immediately — do not wait for symptoms.
Common questions
Which brands are xylitol-free?
Read the ingredient list every time — xylitol also appears as "birch sugar". When in doubt, choose plain unsalted peanut butter with a single ingredient.
