Why do dogs like peanut butter?

Dogs love food, but most seem to hold a special fascination for peanut butter in their hearts. No one knows why dogs love peanut butter so much, but common theories include:

Is peanut butter healthy?

Peanut butter is safe for dogs to consume. It contains protein, fat, vitamins B and E, and niacin.

Homemade or low sodium varieties are great options for health-conscious pet owners. Powdered peanut butter mixed with water is another popular low-calorie variation.

Some commercial peanut butters contain xylitol as an artificial sweetener. Xylitol is toxic for dogs. Always check the ingredients label before feeding peanut butter to your pet!

Peanut butter is notoriously high in calories, boasting 96 calories per tablespoon. Underweight dogs benefit from supplementing their diets with peanut butter. Because of its high fat content, excessive peanut butter consumption can contribute to obesity and pancreatitis. Moderation is key!

The controversy around aflatoxin

Aflatoxin occurs naturally in mold found in contaminated grains and legumes. Because it occurs in peanut products, some people prefer to avoid them altogether.

Aflatoxin was first identified in England in the 1960s. Today, the FDA conducts random checks to ensure peanut products do not contain any aflatoxin. Aflatoxin does not form once peanut butter is packed.

One study reported that when it comes to aflatoxin exposure, commercial dog food is riskier than peanut butter, indicating how unlikely aflatoxin poisoning is in dogs.

Symptoms of aflatoxin poisoning are:

  • Sluggishness, loss of appetite, vomiting, jaundice
  • Unexplained bruising or bleeding
  • Diarrhea
  • Liver damage

Aflatoxin poisoning can only be diagnosed by a vet.

Using peanut butter as a training aid

Peanut butter can be used to disguise pills and administer medication.

You can also use it to stuff kongs. It freezes well and can keep your dog occupied for long periods, making it a handy tool for crate training or enrichment activities.

Peanut butter can be smeared on lick mats, which are useful for counterconditioning/desensitization exercises on handling or grooming.
