The ASPCA's position is that small amounts of coconut and coconut products are unlikely to cause serious harm, but the flesh and milk contain oils that can cause stomach upset, loose stools and diarrhea. Coconut water is separately high in potassium. So: a taste is fine, a habit is not.
Don't make it a habit. Watch for vomiting, diarrhea or a lost appetite over the next day and call your vet if it doesn't settle or your dog seems unwell.
Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
If you're sharing food because you want to treat them, a treat formulated for dogs does the job without the guesswork.

Can cats eat coconut? — Feed with caution to cats.
Not toxic, but be careful — coconut isn't poisonous to dogs, and it comes with caveats that matter. The ASPCA's position is that small amounts of coconut and coconut products are unlikely to cause serious harm, but the flesh and milk contain oils that can cause stomach upset, loose stools and diarrhea. Coconut water is separately high in potassium. So: a taste is fine, a habit is not.
Watch for: Vomiting; Diarrhea or loose stools; Loss of appetite; Belly discomfort or unusual tiredness. Some signs lag by a day — call, don't wait.
The safe amount is a taste at most, as an occasional treat rather than a daily habit. Large amounts mainly cause stomach upset; if that doesn't settle within a day, call your vet.
