Can a puppy eat peanut butter?

Yes, puppies can in general eat peanut butter as long as it does not have xylitol and is unsalted. Peanut butter is a great source of protein, healthy fats, vitamins, and niacin to puppies. However, peanut butter should be fed in moderation as too much can lead to health issues.

To know how much peanut butter your puppy or dog will need to consult your vet, some dogs or puppies may have some health conditions such as diabetes or food sensitivity issues.

What to know before Feeding Peanut Butter to Puppies


Most peanut butter is normally safe for puppies that do not have any underlying health issues.

However, you should be very wary of any peanut butter that has a substance known as xylitol.

In the past, manufacturers did not use xylitol in the manufacture of peanut butter, they used sugar.

But in recent years, people have been avoiding products that are sugary based. Consequently, manufacturers have turned into xylitol as a sugar substitute.

Most sugar-free products such as chewing gums, baked goods, chewable vitamins, breath mints, and toothpaste now use xylitol.

Do not worry though, xylitol is not harmful to human beings but it is very toxic to dogs and is actually life-threatening.

When a dog or puppy consumes xylitol, its body will respond by releasing insulin. What follows is a decrease in the amount of sugar in the dog’s blood, a condition called hypoglycemia.

Hypoglycemia is very dangerous and can even be life-threatening if left untreated. Xylitol’s dangerous effects can set in between 10 to 60 minutes from the time of consumption, making xylitol very fatal.

The good news is that you can prevent putting your puppies or dog’s life in danger.

Before buying any peanut butter for your dogs ensure you check the ingredients first and avoid any peanut butter that has xylitol listed as one of its ingredients.

In case your dog or puppies consume peanut butter with xylitol call your vet immediately.

Some of the signs of xylitol poisoning include

  • Seizures
  • Weakness
  • Lack of coordination
  • Staggering
  • Collapse

Salted peanut butter though not poisonous, should also be avoided if you can as high levels of sodium can cause health issues to puppies and adult dogs.

Making your own peanut butter is even better since you will have control of what ingredients you use.
