Preparation
Check the label EVERY time — some peanut butters contain xylitol (birch sugar), an artificial sweetener that is extremely toxic and potentially fatal to dogs. Choose peanut butter with one ingredient: peanuts. No added sugar, no salt, no palm oil, no chocolate, no xylitol. Natural, unsweetened peanut butter is the gold standard.
Quantity
Small dogs (under 10kg): half a teaspoon. Medium dogs (10-25kg): a teaspoon. Large dogs (25kg+): a tablespoon.
Notes
Peanut butter is calorie-dense — it adds up fast, especially for small dogs. Treat it as a high-value reward, not an everyday food. If your dog has never had peanut butter, start with a tiny lick to check for any peanut allergy.

Feeding Guide
Small dogs (under 10kg): Half a teaspoon — a little goes a long way.
Medium dogs (10-25kg): About a teaspoon.
Large dogs (25kg+): Up to a tablespoon.
Puppies: A tiny lick to introduce it — watch for any reaction before giving more.
Positive Signs
* Obsessive licking and obvious excitement — the universal dog response to PB
* No digestive upset or loose stools
* Healthy weight maintained with controlled portions
* Successfully takes medication hidden in peanut butter without spitting it out
Negative Signs
* Vomiting or diarrhoea — too much fat at once, reduce the amount
* Itching, swelling, or hives — possible peanut allergy, stop immediately
* Weight gain over time — those calories sneak up, be strict with portions
* Choking on thick gobs — spread it thin rather than giving a big spoonful
Preparation Science
Natural peanut butter with no hydrogenated oils retains more healthy monounsaturated fats. The separation you see in natural PB (oil on top) is actually a good sign — it means no palm oil or stabilisers were added. Stir it up and store in the fridge.
Enrichment Science
Peanut butter's sticky texture makes dogs work harder and longer to eat it, which is exactly the point. Extended licking engages the brain, reduces boredom, and releases calming endorphins. It's basically a stress-relief tool that tastes amazing.
Play Ideas
Easy: Smear a thin layer inside a Kong — instant 15-minute entertainment.
Medium: Spread peanut butter on a lick mat and freeze for a slow, satisfying treat session.
Hard: Create a frozen peanut butter Kong with layers — PB, then banana, then PB, then blueberries — freeze overnight for the ultimate challenge.
FAQ
Q: How do I know if peanut butter has xylitol?
A: Check the ingredients list for "xylitol," "birch sugar," or "sugar alcohol." If any of those appear, do not give it to your dog. When in doubt, choose a peanut butter with literally one ingredient: peanuts.
Q: Can dogs have peanut butter every day?
A: In small amounts, yes. But remember it's high in calories and fat, so keep it as a treat, not a food group. A thin smear in a Kong or a tiny spoonful to hide a pill is the right ballpark.
Alternatives
* Almond butter — safe in small amounts but less popular with dogs, and more expensive
* Sunflower seed butter — nut-free alternative, safe and tasty, good for dogs with peanut allergies
* Pumpkin puree — much lower in calories, great for stuffing toys, better for overweight dogs
* Banana — naturally sticky when mashed, way fewer calories, but less exciting
Risks & Disclaimer
Peanut butter is safe as long as it contains no xylitol. This is non-negotiable — xylitol can kill dogs. Always read the label, choose natural unsweetened varieties, and keep portions small. With the right peanut butter, it's one of the most beloved and useful dog treats around.
