Can Dogs Eat Papaya Seeds? Why Vets Suggest Scooping Them Out

By Dial A Vet Veterinary Team

In Far North Queensland, a split red papaya on the kitchen bench is a breakfast staple, and dogs soon learn the sound of one being cut. The orange flesh is a reasonable occasional treat for most dogs. The cluster of glossy black seeds in the middle is a different story. They taste sharp and peppery for a reason, and they are best scooped into the compost, not the dog bowl.

Key takeaways

• Ripe papaya (pawpaw) flesh is safe for most dogs in small amounts.
• Papaya seeds contain benzyl isothiocyanate, a pungent compound that can irritate the mouth and gut.
• A few swallowed seeds are unlikely to cause serious harm, but a bowlful can cause vomiting and diarrhoea.
• Like apple seeds and stone fruit pits, papaya seeds are simplest to remove before sharing.
• Skin, unripe fruit and sugary dried papaya are not good choices either.

Papaya and pawpaw in Australia

Australians use both names. Growers usually call the red-fleshed, pear-shaped fruit "papaya" and the larger yellow-fleshed fruit "pawpaw", but they are the same species, Carica papaya, and the advice for dogs is the same.

What is in the seeds

Papaya seeds contain benzyl isothiocyanate, which gives them their mustard-like bite, along with an alkaloid called carpaine. Benzyl isothiocyanate is the main compound behind papaya seed's traditional use against intestinal worms in people and livestock, and lab studies support that it affects some parasites. That does not make it a safe or reliable dewormer for dogs, and there is no known safe home amount. Your vet can recommend a registered product.

For dogs, these compounds mostly act as irritants. Chewed seeds can make a dog drool or paw at its mouth, and a larger amount can upset the stomach.

Why "scoop them out" is the simple rule

We give the same advice for several fruits. Apple seeds and stone fruit pits contain compounds that release cyanide when crushed. A few accidental seeds are unlikely to matter, but there is no benefit in feeding them, and large amounts add risk. Papaya seeds have a different chemistry, but the practical rule is the same: share the flesh, discard the seeds.

Removal also helps avoid a less obvious issue. A small dog that swallows a large clump of seeds and pulp in one go can vomit or, rarely, end up with an irritated, slow gut.

Sharing papaya flesh safely

• Choose ripe fruit with soft, orange or red flesh.
• Scoop out every seed and the stringy membrane around them.
• Remove the skin, which is tough and can carry sticky latex.
• Cut the flesh into small cubes suited to your dog's size.
• Offer a few cubes as an occasional treat, not a meal.

Papaya contains natural sugar and fibre. Too much can cause loose stools, and dogs with diabetes or on weight loss plans should have fruit only if your vet agrees.

Unripe papaya and latex

Green papaya contains much more of the milky latex (rich in the enzyme papain) than ripe fruit. Latex can irritate the mouth and stomach. Keep green papaya, cut stems and fallen unripe fruit in the garden out of reach.

Dried papaya

Dried papaya pieces are often sweetened and very dense. They are better avoided.

What to do if your dog ate papaya seeds

1. Estimate how many: a few dropped seeds or a whole fruit's worth.
2. A few seeds: no action needed. Your dog may drool briefly or have a soft stool.
3. A large amount, especially in a small dog: offer water and watch for 24 hours.
4. Call your vet or the Animal Poisons Helpline on 1300 869 738 if your dog vomits repeatedly, has diarrhoea for more than a day, or seems unwell.
5. Do not try to make your dog vomit at home.

When it is an emergency

Seek urgent care for repeated vomiting, blood in vomit or stool, a painful or swollen belly, weakness or collapse, or a dog that will not eat or drink.

How vets help

Most papaya seed upsets settle with time or simple supportive care. Your vet will examine your dog, check hydration and may give fluids or nausea support. If a large amount of fruit and seed was eaten in one go, they may suggest X-rays to check the stomach.

FAQ

Will papaya seeds kill worms in my dog?
They are not a reliable or safe dewormer. Use a registered product your vet recommends.

Are papaya seeds toxic to dogs?
They are irritating rather than highly toxic. Large amounts can cause stomach upset.

Can my dog eat papaya every day?
A few cubes occasionally is fine. Daily fruit is not needed in a balanced diet.

Can puppies eat papaya?
A tiny taste of ripe, seedless flesh is fine for most puppies, but their growth food should make up almost all of their diet.

Talk with a vet

If your dog has eaten papaya seeds or another fruit part and you are not sure whether it matters, a Dial A Vet veterinarian can help you weigh it up. Book a Dial A Vet consult.
