There’s a popular trick that’s been floating around dog owner forums for years: feed your dog pineapple and they’ll stop eating their own poop. Whether that actually works is debatable (we’ll get to it), but it raises a fair question — can dogs even eat pineapple in the first place?
They can. The flesh is safe, it’s got some genuinely useful nutrients, and most dogs seem to enjoy the taste. The parts you need to keep away from them are the spiky skin and the hard core, both of which can cause serious problems.
The safe parts and the not-safe parts
Pineapple is one of those foods where preparation actually matters. Unlike blueberries where you can toss them whole, pineapple needs some work before your dog can have any.
The soft yellow flesh is the only part that’s safe. Cut it into small pieces appropriate for your dog’s size. Everything else goes in the bin: the outer skin is tough, spiky, and indigestible — it can scratch or block the digestive tract. The core is too hard and fibrous for dogs to break down, and chunks can get stuck. The leaves and crown are sharp, fibrous, and nutritionally worthless.
Canned pineapple is also a no. It’s packed in syrup with added sugar that dogs don’t need. If you’re going to give your dog pineapple, use fresh. Frozen chunks work too — they actually make a great hot-weather treat.
Bromelain: the enzyme everyone talks about
Pineapple contains bromelain, a protein-digesting enzyme that’s concentrated mostly in the stem and core (which, ironically, are the parts you shouldn’t feed your dog). The flesh has some too, but less.
Bromelain has some interesting properties backed by actual research. It has anti-inflammatory effects — a study dosing dogs with 750 mg/kg of bromelain for six months found no toxic effects and showed reduced inflammation markers. It can also help with protein digestion, which is why some vets recommend bromelain supplements for dogs with digestive issues. There’s some evidence it may help with joint swelling too, though most of that research comes from human studies.
That said, the amount of bromelain in a few chunks of pineapple flesh is pretty small. You’d need to eat a lot of pineapple to get a therapeutic dose. Think of it as a bonus, not a treatment.
About the poop-eating thing
Right, the elephant in the room. Coprophagia — dogs eating their own faeces — is more common than most owners want to admit. The pineapple theory goes like this: bromelain changes the way the poop tastes after digestion, making it less appealing to the dog.
Does it work? The honest answer is: sometimes, for some dogs, temporarily. There’s no published veterinary study confirming it. Some owners on Reddit swear by it. Others tried it and their dog just developed a taste for pineapple-flavoured poop.
If your dog has a coprophagia problem, pineapple is worth trying because it won’t hurt them. But don’t expect miracles. The behaviour usually has deeper causes — boredom, nutritional deficiency, anxiety, or just being a puppy who hasn’t learned better yet. Talk to your vet if it’s persistent.
Nutrition breakdown
Per 100g of fresh pineapple flesh, the vitamin C content is notable at 47.8mg. That’s more than strawberries (59mg) or mango (36mg). Dogs make their own vitamin C, but extra can support immune function during stress or illness.
Manganese is the other standout — 0.93mg per 100g, which makes pineapple one of the richest fruit sources of this mineral. It plays a role in bone health and metabolism. Fibre comes in at 1.4g, not as high as sweet potato (3g) but enough to support digestion. Sugar sits at 9.9g per 100g, which is moderate — less than banana (12g) but more than watermelon (6g). And at 50 calories per 100g, it’s fairly low on the energy scale.
How much pineapple can a dog have?
Pineapple is acidic. Too much and your dog will likely get diarrhoea or an upset stomach. The acidity can also irritate dogs with sensitive stomachs even in smaller amounts.
For small dogs (under 10kg): two or three small chunks, once or twice a week. Medium dogs (10-25kg): four to six chunks. Large dogs (25kg+): a small handful is fine. Always start with just one or two pieces the first time, and see how their stomach handles it before giving more.
One thing people overlook: pineapple is high enough in natural sugar that it can cause problems for overweight or diabetic dogs. If that applies to yours, check with your vet before adding it to the rotation.
Frozen pineapple: the summer trick
Cut fresh pineapple into bite-sized cubes and freeze them on a baking tray. Once solid, transfer to a freezer bag. On hot days, give your dog a few frozen chunks. They take longer to eat, they’re cold and refreshing, and the texture seems to keep dogs entertained longer than fresh pieces.
Some owners freeze pineapple juice (fresh, no added sugar) in ice cube trays as a cooling treat. That works too, but watch the portions — juice has all the sugar and none of the fibre.
FAQ
Can dogs eat pineapple core?
No. The core is too hard and fibrous for dogs to digest safely. It can cause choking or intestinal blockage, especially in smaller breeds. Stick to the soft flesh only.
Is dried pineapple okay for dogs?
It depends on how it’s made. Plain dehydrated pineapple with no added sugar is fine in very small amounts — but be aware that drying concentrates the sugar content significantly. A piece of dried pineapple has about 3-4 times the sugar of the same weight in fresh. Most store-bought dried pineapple also has added sugar or preservatives. Check the label carefully.
Can pineapple cause diarrhoea in dogs?
Yes, particularly if they eat too much. Pineapple is acidic and contains natural sugars that can upset a dog’s stomach. Start with small amounts and increase gradually. If your dog gets loose stools after eating pineapple, reduce the portion or skip it entirely — some dogs just don’t tolerate it well.
Will pineapple really stop my dog eating poop?
Maybe. Some dog owners report success, others don’t. There’s no scientific study confirming this works. The theory is that bromelain changes the taste of digested food, making the faeces less appealing. It’s safe to try, but if the behaviour persists, consult your vet about underlying causes.
Can puppies eat pineapple?
Yes, once they’re on solid food. Give very small, soft pieces — a few tiny chunks at most. Pineapple is acidic, and puppies have more sensitive digestive systems than adult dogs. Introduce it slowly and watch for any reaction.
