Dogs can generally eat peanut butter in moderation, and it's often used as a treat or a pill-hiding mechanism by pet owners. Peanut butter provides a good source of protein, healthy fats, vitamins B and E, and niacin. However, not all peanut butter is safe for dogs — the product must be free from xylitol, a sugar substitute that's toxic to dogs, and ideally should have no added salt, sugar, or oils.

Food Suitability
Plain, unsweetened peanut butter without xylitol is suitable for dogs in small quantities. It can be a useful tool for medication administration or as a special treat during training.
Feeding Instructions
- Check the label: always ensure the peanut butter doesn't contain xylitol or unhealthy additives.
- Moderation: due to its high fat and calorie content, limit peanut butter treats to less than 10% of your dog's daily calorie intake.
- Variety: rotate peanut butter with other treats to provide dietary variety.
Risks
- Xylitol toxicity: xylitol is extremely toxic to dogs and can cause liver failure and hypoglycaemia.
- Obesity and pancreatitis: high fat content can lead to weight gain and pancreatitis.
- Allergic reactions: some dogs may be allergic to peanuts. Monitor for signs such as gastrointestinal upset, itching, or respiratory problems.
Allergies and Sensitivities
Be vigilant for any signs of an allergic reaction after your dog eats peanut butter for the first time. Symptoms can include vomiting, diarrhoea, itching, or difficulty breathing. If you notice any of these signs, stop use immediately and consult a veterinarian.
