Can dogs eat Peanut butter?
In small amounts, with care
In moderation, and only the xylitol-free kind - some peanut butters contain xylitol, which is deadly to dogs. Check the label every time. Plain, unsweetened, unsalted peanut butter is a fine occasional treat.

What happens
Plain peanut butter is a popular treat for good reason - dogs love it, and it is brilliant smeared in a lick mat or stuffed toy to keep a dog busy. The single most important rule is the label: some brands, especially low-sugar ones, are sweetened with xylitol, which is extremely toxic to dogs. Otherwise, the main issue is that peanut butter is high in fat and calories.
How much is safe?
A small smear is a treat, not a meal. Half a teaspoon for a small dog and up to a teaspoon or so for a large one is plenty. Because it is calorie-dense and fatty, keep it occasional and count it towards the daily treat allowance.
How to prepare it
Read the ingredients and choose a plain, unsweetened, unsalted, xylitol-free peanut butter - ideally one that is just peanuts. Smear a small amount into a lick mat or stuffed toy. Never assume a brand is safe without checking, and never use anything labelled sugar-free without confirming it is xylitol-free.
Symptoms to watch for
If the peanut butter contains xylitol, expect rapid signs - weakness, wobbliness, vomiting, collapse or seizures - within minutes to an hour. Ordinary peanut butter in excess simply adds fat, which over time contributes to weight gain and can trigger pancreatitis.
When to call the vet
If your dog eats peanut butter that contains xylitol, or you are not sure, contact your vet or an emergency line immediately - this is a genuine emergency. For plain peanut butter, a large greasy amount that leads to vomiting and a painful belly also warrants a vet call.

Common questions
Which peanut butter is safe for dogs?
A plain, unsalted, unsweetened peanut butter with no xylitol - ideally just peanuts. Always read the label, because xylitol (sometimes listed as birch sugar) is deadly to dogs and turns up in some low-sugar brands.
What is xylitol and why does it matter in peanut butter?
Xylitol is a sugar substitute that is extremely toxic to dogs, causing a dangerous blood sugar crash and liver damage. A few brands use it, so checking the label of any peanut butter before you feed it is essential.
How much peanut butter can a dog have?
A small smear - up to half a teaspoon for a small dog, a teaspoon for a large one - and only occasionally. It is high in fat and calories, so it is a treat to ration.
