Coconut is not toxic in small amounts, but ASPCA notes the oils in fresh coconut flesh and milk can cause stomach upset, loose stools and diarrhea. The shell and husk are an obstruction hazard, never a chew.

More about this food
Coconut is not a poison; it is a fat problem and a foreign-body problem. The ASPCA states that when ingested in small amounts, coconut and coconut-based products are not likely to cause serious harm to your pet, but that the flesh and milk of fresh coconuts do contain oils that may cause stomach upset, loose stools and diarrhea.
The American Kennel Club treats unsweetened, additive-free coconut meat, oil, milk, and water as acceptable in small amounts, and quotes a practical ceiling for the oil: up to a teaspoon or so for a large dog. Scale that down hard for a small dog, and skip it entirely if your dog has a history of pancreatitis, because a sudden fat load is precisely what sets that off. Coconut water is high in potassium, which makes it a poor choice for a dog with kidney disease, and AKC is explicit that it should be offered as a treat and not as a substitute for regular water.
The shell and husk are the hard no. AKC compares them to eating something like sticks or wood and warns they can lead to serious digestive problems and intestinal blockage. A coconut shell left on the patio after a luau or a fiber husk from a craft project is not a chew toy.
In American kitchens the realistic exposures are sweetened coconut flakes from the baking aisle, coconut macaroons and cake, and coconut milk simmered in curry with onion and garlic -- both toxic to dogs, which makes picking pieces out of a dish unsafe. If your dog swallowed shell, or vomits repeatedly, hunches its back, refuses food, or goes lethargic after a fatty coconut product, call your veterinarian or an emergency clinic now; that hunched posture and repeated vomiting is how pancreatitis and obstruction present. Do not induce vomiting at home.
Frequently asked questions
Can I add coconut oil to my dog's food?
In small amounts. AKC quotes up to a teaspoon or so for a large dog, and much less for a small one. Introduce it gradually, because a sudden fat increase causes diarrhea, and ask your vet first if your dog has had pancreatitis.
My dog chewed on a coconut shell.
AKC compares shell and husk to eating sticks or wood and warns about intestinal blockage. If pieces were swallowed, call your veterinarian now. Repeated vomiting, belly pain, and no stool are the signs that push this to an emergency.
Is coconut water safe for dogs?
As an occasional treat, yes, but AKC says it should not replace regular water. It is high in potassium, which is a problem for dogs with kidney disease, and flavored or sweetened versions add sugar you do not want.
