Can Dogs Eat Hearts of Palm?
Mostly yes. Hearts of palm aren't toxic to dogs — the salty canned brine is the issue. A well-rinsed plain slice is fine.

The vegetable is fine — the jar is the problem
Hearts of palm are the tender core of certain palm stems: crunchy, low-calorie and non-toxic to dogs. Fresh, they would barely earn a caution. But almost nobody buys them fresh — they come canned or jarred in salty brine, or marinated with oil, vinegar and garlic. That packaging is where the risk lives, exactly as with olives and capers.
Salt is the real issue
Dogs handle a little salt without drama, but brine-soaked vegetables concentrate it. Too much sodium shows up first as intense thirst and heavier drinking; a genuinely large salt load can progress to vomiting, wobbliness and worse. The fix is simple: rinse the slices thoroughly under running water before sharing, and never let your dog have the brine itself.
How to serve them
One or two well-rinsed, plain slices, chopped into bite-sized pieces, is a perfectly reasonable occasional treat. Skip anything marinated (the garlic and oil matter more than the palmito) and anything already dressed in a salad. If your dog raided the whole jar, brine included, offer fresh water and call your vet if unusual thirst, vomiting or unsteadiness follows.
If your dog ate it
If your dog emptied a whole jar including the brine and seems very thirsty, wobbly or off-balance, call your vet — large salt loads can be serious.

Frequently asked questions
- Are hearts of palm toxic to dogs?
- No. The vegetable itself is low-calorie and non-toxic. The caution is about how it's sold — canned or jarred in salty brine, or marinated with oil, vinegar and garlic.
- How should I serve hearts of palm to my dog?
- Rinse the slices well under running water, then offer one or two plain pieces. That washes off most of the surface salt and any brine clinging to the layers.
- My dog drank the brine from the jar. Should I worry?
- A small lick is usually just extra thirst. A large amount of salty brine is more serious — offer fresh water and call your vet if you see vomiting, unusual thirst or wobbliness.
